Best frozen seltzer:
CANADA DRY

It makes a very flaky soft soda ice. It melts in your mouth and gives you a reason for living.
Most dangerous seltzer:
TRADER JOE'S

While this makes a very decent soda ice, when you crack it, it pops something fierce. Pieces of flying ice has often gotten near my eye. Be careful freezing this brand.
Most Flavorful:
A tie! TRADER JOE and POLAR ICE

Trader Joe's seltzer water, despite its dangers, has really strong flavoring, overwhelming at times but good.
Polar Ice has the most interesting flavors. My favorite? Granny Smith Apple...it's extremely refreshing when frozen.
Most boring:
VINTAGE

Great drinking seltzer water, but when frozen it is just kind of blah. Also it usually freezes too hard so it's not as soft on your teeth as the other kinds.
The researching continues. Let me know what I've missed.
