I've had many 2c-i experiences, and only one 2c-b experience. I enjoyed them both, but they are different. For me, 2c-i lasts alot longer, is more stimulating, more visual, and more possibility for mind fuckery. 2c-b was alot more euphoric. Neither one is better than the other, but I'd say I liked 2c-b better and need to try it again for a better opinion.
