Have never encountered a number of items mentioned here.
Ting grapefruit soda: pretty good, haven't seen it recently.
Sanpellegrino chinotto and Sanbitter: I do seem to like some bitterness, and the portion size suits me.
Bundaberg ginger beer: Good, but wish they stuck with the smaller bottles.
Vernors, Canada Dry: IMO, mostly tastes like sugar water.
Dr. Brown's Cel-Ray: One of those things which sounds awful but actually works.
Red Bull, Monster et al: I gotta really be dragging to want one, and even then, I'd want the original small can size. Not surprised Red Bull originates from steamy hot Thailand.
Zevia: It's okay but not something I actively seek out.
Coke Y3000: I kind of liked in the 6 oz mini-cans, served ice-cold.
Starry: As a replacement for Slice, a step in the right direction, but still too syrupy-sweet.
Virgil's Root Beer: Pretty solid.
Suntory CC Lemon: Lightly carbonated, nice balance of mild tart and sweet, IMO.
Have tended not to care much for "cream" type soda, nor kombucha-based drinks, but the latter are mostly inoffensive, 'cept for the price ($5/can?).
