SWIM has a lot of experience with 2c-e, and it is one of his favorite phens. It is powerful and has had a lot of depth for him. He never had much of a bodyload with it and doesn't understand the 'not user friendly' comment, although he has heard it from others as well. It can be quite intense, for sure. Perhaps the sense of euphoria is not as strong as with other phens, but it's very useful and, in his opinion, is quite enjoyable.
2c-c SWIM has done twice. It was interestingly visual the first time. It made things hazy and thinking was slowed, almost like taking a hit of good weed. It was fun, and things were hilarious. It was a great one to take with a few friends. He did not find it to have much depth or interpersonal qualities. It was enjoyable though. 2c-c was comfortable and calm.
The OP didn't mention it, but SWIM would like to recommend 2c-d. Aside from 2c-e, 2c-d is his favorite 2c. It's comfortable and very forgiving. He cannot see this one getting out of hand unless the dose was too high. His favorite thing about 2c-d is that it leaves you very lucid and 'there' so to speak. Adding to this state, it seems to be very intellectual. This substance definitely caters to deep thought. It isn't forcefully introspective, either. You can easily control and turn this thought towards anything you want. SWIM really likes it.
People say that 2c-c and 2c-d are 'weak'. SWIM feels this way when compared to 2c-e, too. Neither are very intense, and you do literally have higher dosages with these two. However, as he said, he really thinks there is something to 2c-d. It's really unique.
He hasn't tasted any of the other compounds listed, but he's excited to try 4-aco-dmt.
