I haven't used either of them since the official WM6.5 update, but I did go back and forth between the two for a while. What I found was pretty much as people are already saying.

NRG is VERY nice looking and stylish, but I've had stability and speed problems with all the flashy ROMs that came from him.

MR has had a couple that had stability issues, but for the most part, I've only had good experiences with MM's ROMs. However, they don't look nearly as nice as the NRG ones.

I had problems with the Sprint 6.5 official at first, but after hard resetting and clear storage about 4 times, I have had no issues except for the occasional slowness showing up after several days without restart. The only thing that slows the phone down, it seems, is the Messaging application...which IMO has always sucked and has been a downfall of WM since I've been using it. I use Cookie's Home Tab with it and have no reason for custom ROMs.
