I'm curious - how many people who voted in here have actually tried more than 2 or 3 of them? I even nearly voted myself and I've only tried 2C-E.. I imagine results could quite skewed that way. Maybe it'd be good if there was a multi-choice poll above with "Which 2C-Xs have you taken?" that way if for example 30 people voted for having taken 2C-I and 29 of them listed it as their favourite 2C-X, while 150 people voted for having taken 2C-P and 50 people voted for it being their favourite, it'd give a more accurate picture, rather than making it look like 2C-P was preferred, when in fact on average, a higher percentage of users liked 2C-I.
Just a thought.
Anyway, I love 2C-E, but, as I mentioned, it's the only one I've tried so I can't really vote I'm most interested in trying 2C-B, 2C-T-2, 2C-P, 2C-C, in order from most interested to least
