In my testing, 2x2 vs 4x4 with mu-mimo on the AP was almost unnoticeable for home wifi (with the exception of a few clients that had 4x4 radios), and some papers/blogs I've seen showed mu-mimo does very little in enterprise wifi as well. Massive MIMO in mobile and fixed wireless is a different story, big gains there. We routinely got 2-3x mu-mimo gain with 450M. 16x16 mu-mimo in wifi might be useful for something like a stadium or other wide open space with dense clients, but not much else IMO.
