I'm a Canada Dry guy.

I was going to try the Fever Tree as I've had their tonic which is solid albeit on the pricey side, but there were quite a few recent reviews claiming the formula has changed and it's not nearly as good as it used to be. Perhaps the FT fans can comment on that.

Bundaberg
Jackson Hole Soda Co
Vernors

In that order

Orca Beverage Soda Co's Americana honey lime ginger ale for those of you in the pacific NW :D

Bruce Cost Fresh Ginger Ale
Bundaberg

I like Fever Tree Ginger Beer and Lemon but haven't tried the Ginger Ale.

My SO swears by Tom Tucker gingerale. Local to PIT. I like Canada Dry and Schwepps.
