Most people don't create threads here unless they have a problem, so it makes sense that what you'll see posted are issues.
My brother's Note 4 on MM (VZW) has no problems whatsoever, and both my Note 4's on KK and LP (VZW) also have no problems.
However, it does seem there are more reported problems with AT&T's release of MM. AT&T took a "very" long time to release MM after the rest of the carriers had done so, so maybe there's a reason behind that.

That's up to you. Coming from someone who has owned a Note 4 for 2 years, all I can say is... YMMV!
