2C-I is pleasant by its self or in a cocktail. And works well for people who are unseasoned with tripping. 2C-P still being my favorite with 2C-E a very close second when it comes to the 2C-x's. Visually profound trips is one of the best qualities when it comes to psychedelics IMO, and in that aspect like 2C-B, 2C-I for some feels "empty"
Could be people expecting to much from a chemical in the same family as others thinking they should gauge their experience compared to another. Me, personally, prefer to understand the effects and then take the chem with an open mind, not comparing to another because every trip is different and I think it takes away from the possible positive attributes each chem provides.
Sorry for the ramble half gram of caffeine does it too ya.
