I'm not completely sure what you guys look at but if we go by making an impact, winning when booked, building heat, winning the top championship, and the lot; I'd have to honestly say Shades. It's hard in my opinion to top the guy who came in with guns blazing, shocked the world by cashing in successfully on Eli James, and has been more than vocal about taking on all comers. Maybe I noticed those things more since I have been working closely with him, but they're all true.
Loverboy is good, and I like his work. I enjoyed his mention of the Nash/Adjective blunder in one of the RPs I saw of his and I like his ability to stay relevant with wrestling, but if memory serves right he lost matches and lost the x-treme title, and ducked challenges for cash vs cash matches.

That's all fine and all, but not really sotm material in my humble opinion. And being close last month doesn't really apply to this month; it just means he lost last month. I'm totally not trying to sound like a dick here, btw. Just being honest about what I've seen.
I'd definitely, however, agree the other name worth mentioning is Doc Dville as he's been very solid and I think he won most of his matches. If you look at who was active for the full month from start to finish, Doctor D should probably get it. If you go by my earlier points, it's probably Shades. Is there clarification posted anywhere as far as what's actually looked at for sotm?
