Super U does have a much bigger selection of wine than Leader Price, yes, but LP does have some great specials. I got some champagne to use for mimosas last time for 1.95E!!

Super U does not have much in English, no, but they are a better choice for first day supplies than Leader Price, as LP really doesn't have a lot of that kind of stuff. You could try Hope Market, which does have most of the first day supply stuff and they do have a lot of products in English. We went there to HM on the recommendation of a friend and it was OK, although I personally didn't find it clean. You can also check out Petit Casino in the Village. They have US products, including US junk food and the prices, while higher than Super U, aren't horrible. PC, Super U and Leader Price are all VERY clean, as compared to Hope Market. And depending on where you're staying, you could head over to one or the other of the small Carrefours, either at Porto Cupecoy or Jordan Village. They have lots of US stuff there. The one in JV is better stocked than the one at PC. All the Carrefours are very clean. Based on personal experience, the Carrefour at Cole Bay doesn't seem to have nearly the liquor selection of the one in P'burg, and their wine specials were pretty lame. The Carrefour at Cole Bay isn't far from the French side, but not sure I'd bother with going back there on the first day.
