i like both of these alot. I've taken 2c-e more than any other 2c, probably about 25-30 times over the past few years. I've also tried 2c-c, d, i, p, & t2 for points of reference. It seems to be the most user directed of the 2c's when it comes to mood/euphoria/dysphoria. The visuals on it are great, pretty impressive as low as ~10mg for most people. I have used it therapeutically a few times as well when i was having trouble with important decisions and avoiding the issue. These aren't the most pleasant of trips, but certainly productive, and the end of trips like these is usually very rewarding. I've also used it recreationally at music events and the like, also certainly a blast, but more of a risk as its in an uncontrolled environment. I've also taken it with a significant other and stayed around the house watching movies and/or doing the freaky trippin fuckfest thing

All in all, one of the more useful 2c's. In the book Higher Wisdom, Shulgin named 2c-e as the most potentially useful of his creations. And that's probably as informed an opinion as you'll find, but an opinion nonetheless. It does have a tendency to bring issues you may be having to the forefront though, so if you're looking for escapism from some problem, this isn't your drug. I usually like to take 18-22mg, and have gone higher, but I've got some stuff to work out before i go back to the 25-30mg range. Even at lower doses it can be a bit manic, fast loopy thoughts, desire to smoke (if you're a smoker) and potentially pace when approaching the peak. Cannabis certainly enhances the visuals, but makes the mental aspects less clear.
I've only had the chance to try 2c-p (at an active dose, did some <1mg testing a week or so before) once so far because of the lengthy duration, but i had a really great time, and at only 9mg. I used 2 AWS Gemini 20's to sextuple check the weight of the empty capsule, then added about 5mg, commenced with borderline ocd weight checking, then continued adding almost imperceptible amounts of 2c-p & doing more obsessive weighing til i reached between 8.5-9.5mg. Strange little ritual.
The long duration is not quite as long as it seems because, IME, for about 2.5-3 of those you're more or less sober, with a slight stony feeling. 2c-p was very relaxed for me, almost as relaxed as 2c-c, but not quite. Other than that it was not terribly different from my experiences with 2c-e. Visuals were similar, but a bit fuzzier, slightly more euphoric than my more recent 2c-e trips, but i've had 2c-e trips that were equally if not more euphoric. Mentally & physically it felt a bit like 2c-e in slow motion, if that makes any sense. I felt rather sedate, but awake for the duration of the experience, but this could've partly been due to me getting extremely stoned on hash & eating a bunch of carryout from a local italian restaurant during the comeup and laid on the couch feeling very stoned and full during most of the comeup. I laid on the couch watching cartoons for a while enjoying myself. Then went to a bar with a couple friends for a couple pints & caught some music, though frankly i was more interested in the people watching than the band. The band was quite musically talented, but some of their song choices weren't exactly my thing, but i was able to appreciate it objectively. Conversation felt a tad forced, but not too bad, I was still able to make jokes that people who weren't tripping found funny. went home, listened to some more tunes, watched a bunch of king of the hill, drank another beer or two and went to sleep relatively easily at about T+14.5, so all in all i was only really tripping for 11.5hrs, though when i woke up and went from the couch to the bed a couple hours later i still had some minor visual activity going on. Think i'm going to try 11 or 12 this weekend. Overall I found 2c-p, in my limited experience to be the 2c most similar to mescaline, or cactus extract rather, never had synthetic or otherwise purified mescaline, though a bit less clear headed.
hope that helps
