I think I mostly use both there are times where it seems where I can't seem to find the drinks so I'll settle for Super Potions but if there are drinks I'll normally just buy a lot or fly back if have to however there are times though where as their HP gets higher I'll get Hyper Potions to back them up so basically I think I'd go either way but I mostly prefer the drinks especially in the in earlier stages of a game especially choosing Fresh Water or Super Potions..because they restore the same amount but it's less money and I find when I overbuy Super Potions I end up with much less money :> although I wonder if Fresh Water and Fire types go together..

As dumb as it sounds, I usually don't. I constantly rotate my Pokémon around and make frequent Pokémon Center trips, so I don't use either very much at all unless I'm in a bind. d:
