99% of the time I just drink water and treat juice and sodas more like a dessert. When I do drink soda though, I really like Jarritos. Lime is probably my favorite.
Manzanita Sol (an apple soda) is also really good. Not too many people I've shared apple sodas with like it here in the states, I'm not sure why. Highly recommend it.
Then of course there's Coca-Cola. Real cane sugar only.
And my most recent soda is Mountain Dew SPIKED. It doesn't have alcohol in it (though I certainly recommend adding some rum to this) but it is really fucking good. They've got prickly pear juice in them and it adds a nice unique flavor.
Other than these I pretty much just won't drink soda if given the option. Soda has a lot of sugar that I'd rather consume through other means. I do like trying the occasional craft soda, but I can't think of anything specific. It's usually stuff that's hard to find like strawberry cream soda or cucumber soda. And speaking of cucumbers, the cucumber and lime flavored Gatorades are Nagasaki level satisfying.
