MOBU has way too much black for anything but the deep woods, in the West anyway. It's one of my pet peeves that, when you go to a sporting goods store in the desert Southwest, and everything
outside is tan or reddish, damn near everything
inside the store is MOBU. Might as well BE black.
WRT their clothes, I have one of their shirts (Brush camo in lightweight nylon for hot weather hunting) and it fits well and has held up well.
As far as camos go, Natural Gear, Multi-cam, Cabela's Outfitter, etc. probably make more sense than most "realistic" camos other than maybe something like Brush, Max-4 or similar for specific environments where the background is a bunch of small lines, not big masses of color. Of course, random lines would probably work as well as images of brush or stalks, but they probably wouldn't sell as well.
For a "realistic" camo, Realtree APG seems to be pretty good: they've included enough realistic images to attract hunters, but designed in enough actual camouflage to break up your outline in many environments.
That and something like King's Desert Shadow.
