Yes, Orangina is definitly in another league. My first bottle of it practically ruined all other soft drinks for me, can't stand them anymore.
Besides certain kinds of sparkling mineral water it is practically the only carbonated stuff I drink once in a while.
Oh, and I also like Bionade which is also not so sweet and slightly bitter tasting because of its malt basis.
But Bionade is probably even harder to get than Orangina in most parts of the world...
