So, I've now tried 2C-B on several different occasions and can attest to what DutchBloke says about having very different experiences each time. I've always read what a huge impact setting and situation have on your experience, but it's something else to experience it firsthand.
My first experience was with a group of five close friends at my house. We each took 20 mg except for one who still didn't feel anything until he took another 10 mg upon which he had what he described as the same experiences as us. This was by far my favorite, with us sharing the same crazy, colorful visuals - mainly breathing, morphing, and some fractals - and the same extreme pleasure from trying different foods (we all ended up with diarrhea the next day from having eaten way too many different things and strange food combinations - LOL!). We tried going outside, but there was a cool breeze that made us uncomfortable and some of us got pretty paranoid that we were being watched. We enjoyed listening to music, but I had a lot of trouble focusing on it and couldn't even tell what song was playing most of the time. We all felt very giggly and giddy throughout the experience.
My second experience was with the same group of friends and the same dosages, but this time at one of our friend's homes. The come-up felt much faster this time, even though I had eaten a moderately-sized meal a few hours prior. I was the first to feel effects about 15 minutes after taking my dose. We had still laser lights turned on in a dark room and they'd begun to look like twinkling stars and appeared to float around on the ceiling. The floor boards in the living room also appeared to flow like water. This time we all had slightly different experiences and had a bit more trouble relating with each other. Food was still very enjoyable but not as extremely pleasurable as last time. We all shared an increased fascination with art and spent almost half an hour observing art works around the house. Three of the group claimed that they could see a panda sitting in one of the trees in a painting of a forest and that the trees appeared to sway in the wind. One friend, who usually finds art very boring, said it felt like each painting was speaking to him, and spent an extra half hour looking up different art works and analyzing what they might mean. The same feelings of giddiness permeated the experience as last time and there was a lot of giggling, but about two hours into the experience I began to feel somewhat depressed and like nobody in the group could truly understand me. I felt an intense sense of loneliness in the world despite being surrounded by my closest friends and had a strong urge to self-isolate. I first went to a bathroom, where the visuals became very intense. I spent some time watching the floor tiles, which appeared holographic and constantly changing in design. Then, I caught a glimpse of my face in the mirror and it scared me because it appeared deformed and I could not recognize it as my own. I then went outside with a couple of friends and the trip took a positive turn again as we spent some time rolling around in the grass, which felt incredibly soft, and watching the stars and airplanes.
Next, I got brave and tried the same 20 mg dose at a local music festival. At first, the experience was very pleasurable. It appeared to hit even faster and stronger than last time, with effects kicking in within 10 minutes. I felt giddy and energized, and spent about half an hour dancing non-stop to Ghastly. The effects continued to intensify and I could no longer pay attention to the music. It faded into background noise and I spent the rest of the set sitting at the sidelines simply observing my surroundings. The grass field appeared to flow and undulate like water, and the feet of those passing by appeared to sink into it. I found it very funny and could feel my face getting sore from nonstop smiling. The sun was particularly bright and brilliant, and the clouds were simply marvelous. My favorite part of the trip was lying down and watching the clouds flow, swirl, and morph into many beautiful shapes and patterns. Then, the confusion began to set in. I can barely remember the next couple of hours of the trip, only the distinct feeling of being outside of myself, my body not being mine, hearing people talk to me but not understanding what they were saying, and trying to touch my arms and poke my face with my glasses but finding the feeling very dull and numb. I became preoccupied with the thoughts of why I felt this way, why I couldn't understand what was happening around me, and how strange it all was. I kept repeating to myself that this is all due to the unfamiliar setting and that I should just ride it out, which helped avoid the onset of panic. The confusion wasn't unpleasant, but it wasn't fun either. At one point a friend brought me an ice cream cone and I remember staring at it for what seemed like an hour (but was probably only a few minutes) just wondering what this object was and what I was supposed to do with it, until my friend finally pushed my hand towards my mouth and talked me through how to eat it. After the peak of the experience finally waned, the confusion faded and I felt very very happy for it to be over. The trip returned to a similar feeling as the onset, and I spent the next hour enjoying the remainder of a Marshmello set (who I hadn't realized was already playing due to the confusion), just dancing nonstop and simultaneously watching the clouds. I decided that day that if I ever try 2C-B at a festival again, it would be at a lower dose than usual.
And that I finally did at EDC last weekend, with only 10 mg during the second half of the night. It gave me a light energy and mood boost, made the music seem louder and clearer, made lights and colors brighter, and gave me some mild breathing and flowing visuals. I didn't notice any changes in sociability and no confusion, though sometimes the increased loudness of the music became a bit overwhelming. It was an overall enjoyable trip.
Aaand, those are my experiences with 2C-B thus far that I just wanted to share with you all.

Each trip has been pretty unique and it has been interesting observing the effects of different settings and situations on the trip. All experiences described were from the same batch, and the doses were measured out with a milligram scale. I am yet to try any other 2C's, but I will probably save 2C-E for much later in my journey thanks to Xorkoth's and other's comments on it.
