Cocktail sauce is ambiguous ( to me anyway) but both are wine killers. Slightly surprised to see it mooted here.
The North American version probably worst and I just about never use it any way.
The version I grew up with (I’m from the Prawn Cocktail Years) and do make from time to time (tarted up with some cognac tarragon and a touch of Dijon).
For that, I tend to look for a fairly neutral white ideally not expensive and just a small pour to assuage those who can’t eat without wine. Or SA Chenan Blanc and Fino sherry too.
If it has butter, IME, it works best with something with both lots of body and lots of acid. That’s what I’d look for, regardless of region. You can find it in Champagne or Jura or Chablis or Fruili or Albarino or Fiano di Avellino. But it’s more about the individual bottling than about the region.

I’m a little surprised there is only one Sauvignon Blanc suggested. Dungeness is really sweet, and I find it goes amazingly well with Sav Blanc, which would mean Sancere.
If you try it, post here and let us know what you think. I did this with my cousins two weeks ago with some fresh Dungeness and a nip from four different Oban bottles: 14, 18, Little Bay, and…I can’t remember the fourth. Shocker.

Mostly sav blanc with a hint of semillon, nice body without the chard fatness. Decent acidity, no malo. I think it’s a lovely pairing with crab.
Dammit, now I want crab. Every year, my friend and I buy about 2 crabs/person, and we eat nothing but the crab until we can’t eat anymore. It’s glorious, especially with champagne.
