So I made edworts pale last week and split a 10 gal batch between a carboy and plastic bucket. Carboy Krause dropped about 7 days after pitch....just opened bucket and it’s got a huge foamy krausen at 13 days....used us05 for both....should I repitch?

No- if it's got a krausen, it's fermenting.

Why would one go before the other? Same wort, same temps kept together...maybe one yeast packet was older?

No idea, but what would pitching 100,000,000 to 200,000,000 yeast cells into something that easily contains several billion active yeast cells accomplish?

Also, it’s reached final gravity at 10.11...

The one you want to add yeast to is at final gravity?

Yah I didn’t know that til a few mins ago when I got a chance to take a sample, but it’s still gotta thin krausen on it which I feel like I’ve never had in us-05 after a week

So vessel geometry has been shown to have at least a little bit of impact on fermentation.

Different yeast packs, maybe one vessel had the clear wort, one had the stuff from the bottom of the bk, O2, whatever, all could play a small role in why one is different than the other. It is interesting, but I'm not thinking it is something to worry about. If you bottle definitely wait until the gravity is stable for at least a few days before moving on.

Maybe not related but I had one batch that stalled out, then restarted later. That would account for the late krausen.

Actually, I was thinking about this last night; The carboy had all the hop debris and trub since it was racked first, the bucket was clear wort, so that could have played into it as well.
