I found DXM far more visual than K/MXE. That being said, K > MXE > DXM. I don't get OEVs even on high doses of K/MXE, but I definitely get heavy distortions, double vision, and warping.
From what i've heard, pure pcp beats all the dissociatives in terms of visuals. Not the most pleasant visuals.....my buddy told me he saw his sisters head start spinning uncontrollably like the girl in "the exorcist". He said "it was terrifying to say the least".....so yeah. IMO dxm "movies" and "wormholes" you have in your head are by far my favorite visualization off any drug.
