I get pretty similar speeds out of my AC-M, AC-LR and nanoHD, but since I have 3 AP's, none of them ever have a large client count. Plus all my devices are only 2x2 at the most (867Mbps).
I think the AC-LR would be fine for most households with it's unique antenna design to help mobile devices communicate better.
