I wondered the same thing when I started vaping
my Lady uses the high juice (36) I use the medium at 18, but I'm interested in lowering my nicotine intake, so I've been messing around...
I tried them all from high to the 0 nic stuff, and to be totally honest, the flavour has been the same for the "same flavours" for all...
I'm not sure if I'm ready to go 0 nic, but I DO know it won't be the taste that will be the deciding factor!
cheers,
snuggs
