I find 2C-B is overrated. It's fun and nice, but maybe a bit bland or generic for me. Lots of people love it though, so it's worth checking out if you get the chance, but don't feel like you're missing out if you never find it, there's nothing that special or unique about it IMO. 2C-I seems about the same, but I think I only tried it once.
2C-E and P are really worth checking out though, good you have it in your stash!
