Why so few peaked glacis plates on AFVs?

Why do so few armoured fighting vehicles have peaked glacis plates like Russia’s JSIII heavy tank?

Soviet soldiers even

JS series tanks may have been rather short-lived.
OTOH French armoured cars like the EBR and AML series enjoyed long production runs and long service lives.

It’s incompatible with ceramic composite armor. It probably doesn’t work well with or is made redundant by ERA too.

Several reasons.

Straight angled glacises are much easier to repair and maintain, they are also easier to manufacture, fit and weld. ERA is a non-issue.

It's here, in a rounded cast form, a change from the flat plates of the M47

As in earlier threads, having really sloped armor on the Pike, cuts down on _usable_ while have space that gear really couldn't be placed into interior space

Cramped, esp. for the size of 122mm rounds

I read somewhere that to load the gun had to be raised to max elevation to get the shells into the breach!

Which was changed again on the M60 for the reasons I mentioned above.

On Paper, the JSIII/T-10 looks awesome

But given the ergonomics, limited ammo, and slow loading at that, was more a Cold War Boogeyman than effective weapon. Would have been better with a slightly larger turret, and 100mm gun
