M22 Vs. DTV4

I currently have a V4 and use it on a Drag 2 if that matters. I've been looking at the M22 and am curious from other perspectives if one is better than the other and in what ways. Any input is accepted.

Currently waiting for the SiC bucket for the V4, but I've seen alot of great reviews for the ESCC for the M22, which is what I would probably get.
