I haven't had 2cB or 2cE but i like 2cD & 2cC Better than 2cI. The duration and body load of 2cI was a bit much in my opinion. Not as heavy as 2cT2, 2cT4, and especially not as intense as 2cT7. The thios seem to have a different flavor than the Halos. Want to try 2cP, but still like 2cD the best followed closely by 2cC.
If you want more of the entactenogenic effects i would recommend a phenethylamine like 6-APB or 5-APB. Smoking some good buds with the 6 makes it a bit more psychedelic than normal. The 5 is a nice social tool.
To be honest my favorite is aMT. It truly is the "Rolls Royce of psychedelics"
