When I was in Japan, I realized I liked Pocari Sweat (sort of a fizzy Gatorade-ish thing).

Orangina is one of my all time favorite sodas. The Pellegrino equivalents are really good too, though I hate the super bitter one...I don't know if they even make it anymore. It's not on their website and I can't remember what it was called. It sort of tasted like Campari.
