WI: Sweyn Knutsson does not die in 1035?

Canute the Great's eldest son by Elfgifu of Northampton, Sweyn (https://en.wikipedia.org/wiki/Svein_Knutsson), was King of Norway with his father until 1035, when he was driven out by Magnus the Good, son of King/Saint Olaf II of Norway. It's then mention that he died between then, but before his father.

What if Sweyn had lived? IOTL, England and Denmark were divided between his remaining sons, Harald and Harthacnut. Then, when Harthacnut died in 1042, Denmark went to Canute's nephew, Sweyn Estridsson, and England went to Edward the Confessor. Would Sweyn's survival have made the situation better or worse?

Any thoughts?

Better or worse is a strange metric.

Different, well, it depends how things fall out. Are you putting the PoD post Olaf running Sven out of Norway?

The other question is whether this keeps Ælfgifu alive/in power.

You could end up with an interesting dynamic in England. Emma and her sons lined up against Ælfgifu and hers. IIRC, Ælfgifu's family was connected to the midlands bloc headed by Leofric of Mercia. There'll be others opposing said faction - likely Godwin amongst them. Which would be ironic, seeing as in OTL, Godwin did for Ælfred, Edward the Confessor's brother. Unless the PoD is after the incident at Guildford, when Godwin has definitively thrown his weight behind the Knutlings, rather than the line of Cerdic.
