You've asked for opinions about Victoria--I wonder if you hate her, depriving her of Albert.
It's just my understanding Albert made her very very happy OTL. Maybe he wouldn't have the same effect on your ATL differently raised Victoria, and maybe you have some other consort in mind who will make the ATL woman just as happy.
But--I think Victoria's legendary satisfaction with her husband was lottery lucky, despite her considerable agency in the matter of who to pick, because I think Albert's willingness to please was a rarity in his class. (And that may mean that in the ATL his own character is butterflied and he does not develop this noteworthy character nor focuses on Victoria himself).
I have to admit, a small amount of butterflying does seem likely to mess up the OTL good thing they had going. Perhaps it should be an ATL principle, that whatever was superlatively good in OTL should become flawed in ATLs and a few other random things that were mediocre in OTL should become excellent in the ATL. So--the chemistry between Victoria and Albert is a combination of her own character (changed), his own (changed, and likely for the worse because he was good beyond reasonable expectations OTL) and circumstances and opportunities (scrambled).
So, is Victoria herself better off? Probably she is less happy at her personal outcomes. But maybe her ATL childhood was more conventional for her class? Perhaps therefore more enjoyable? Maybe she pays for a happy, easy childhood by being stuck with more conventional women's burdens, an indifferent husband, a lack of respect as a person in her own right? And from there I could see it going two ways--one, she discovers her inner OTL Victoria in belated adversity and one way or another fights her circumstances and wins, for a certain value of win. For instance--I doubt it could go so far as she divorcing a husband who displeases her and taking another. But, what if it does? She'd be asserting the primacy of the British monarch regardless of sex-succession rules load the dice against women becoming the sovereign, but when they do so under the rules, the Queen remains Queen, her husband is mere consort--and per the precedent of Henry VIII, they are expendable! And for no more weighty reason than the Queen's displeasure he can be set aside--I presume if Victoria had a son with this husband British politics handpicked for her for reasons of state and dynasty, she will claim the son for her own and as the heir to the throne, but reject the father. The children of her body are hers.
So if she is more of a conventional woman discovering unconventional strengths in adversity, perhaps she is more doting and attentive of her own children? Possibly, having borne a sufficient number to ensure succession, she foregoes marriage after putting her husband aside? That would certainly be less scandalous than taking another mate more of her choosing--but that in turn would be less scandalous than turning up pregnant without having taken another husband first!
So it boils down to me wondering--are you messing with a life that on the whole and in its middle especially was a happy one, and that bears great dignity to this day, just for the sake of rolling random dice because you have to? I'd say no you don't have to, you could just as easily, despite say a different War of 1812 having butterflying effects all over Europe, argue these were minor and damped out in British and German royal/noble circles, and Victoria and Albert are essentially the same people with the same interests, and likely enough to meet. You could simply butterfly Albert, or just kill him off, and indulge the game of "who would Victoria pick if she didn't have Albert to choose?" If instead you want Victoria herself to be different--is that good or bad for the United Kingdom? My impression, which may easily be mistaken since I've never studied her in an careful and balance biography or history, is that as a person and a monarch Victoria did on the whole a lot of good and exhibited strengths of character that put her above the common run of monarchs of her era. She could be and was from time to time selfish, but not inconsiderate.
Conventionalizing her early girlhood might result in her being more conventionally happy as a child, but deprive her of that character and the true basis of her power as a historical figure--even if constitutionally speaking as heiress she is Queen and no consort could steal that, it would perhaps be a matter of running roughshod over her as a woman and making sure she is not in a position to make waves about it that might first of all condemn her to a lifetime of worse misery than anything she suffered OTL (save perhaps the loss of Albert--a misery she might be spared if none of her children pre-decease her--she might actually care a lot about them in the ATL) and consign her to footnotes in history reserved for consort queens and US Presidential First Ladies. We think of the Victorian Era as patriarchal now--but imagine if Victoria's influence were removed, would it not become even more so? Perhaps close study of Victoria would lead me to the impression she made those things worse in OTL and we'd be better off with someone less remarkable than her, but the way I'd bet is, a strong woman generally leads to better balance in the gender wars. There can at any rate be no doubt OTL Victoria was strong; it seems you are setting her up in the ATL to be weaker.
Or perhaps as I was suggesting, a late bloomer--she goes into the wringer presumed to be a malleable and obedient little girl who will do what the powers that be tell her to, but as events unfold and the true terms of her compliance become clearer to her, she finds that vixen force that Elizabeth 1 exemplifed and that her OTL self shows, and starts to fight back. And perhaps, by the time the dust settles had won many a feminist battle, or at lest one or two crucial ones.
I myself would not have chosen to mess with her life or character much, and thus would assume a life closely parallel to OTL. Since it is your choice to do that for your own reasons, only you can judge which sort of course you'd think the ATL woman would take--turn out with a similar disposition despite ATL training, and behave essentially the same way because character shines through, but perhaps she just misses her chance with Albert? Albert gets taken up with some other woman first? Or does different upbringing make for a different person, who chooses everything differently? Does this leave Britain in general, and British women in particular, better off or worse off? Or would you say Victoria was completely irrelevant to the deep trends of European and British society? (I doubt you would, but I might be surprised!) Are you angling for a certain effect, or just shuffling the deck and playing the cards you are dealt?
For instance, would you want to see British society shaken up over gender roles--or would you believe that any attempt to do that would inevitably call forth unstoppable reaction, so any evolutions have to happen but slowly and subtly. Would you want subtle trends to drift in different directions than OTL, resulting in a subtly yet distinctly different set of mores by 1900? Or were you looking at the romantic life of Victoria through the lens of dynastic politics, unconcerned about her personal feelings but with an agenda for dynastic connections for Britain? Do you feel that perhaps if Victoria were a different person, her own children would be happier and more responsible in their actions, and later generations of Britons would reap benefits sowed nearly 100 years before?
