I wouldn't start with 2C-I, it had a very uncomfortable and pervasive body load the first and only time I really tripped on it (but I also did 40-50mg which is a pretty high dose).
2C-B was my first real psychedelic experience and it was fantastic. Very worthwhile but forgiving chemical. The mindfuck aspect is very different from other psychs since you can kind of decide how intense it is. I haven't tried 2C-C or 2C-D but have heard they are both provide pretty flexible experiences too.
When I tried 2C-E I only parachuted 11mg, and while it was a very light and manageable trip, there was no real euphoria or anything, probably wouldn't qualify as "recreational" imo. Still, a decent psychedelic for sure.
NBOMe-Mescaline looks like the most worthwhile new psychedelic RC, really wouldn't mind trying some out, it's just too expensive for me.
