I have deployed some low-end HP access points for mesh wifi in a buddy's house, 3 years and no issues
I deployed the new Asus mesh WAPs in a CEO's house and they have been good so far.
I want to try out the Cisco Meraki GO AP's. I have their enterprise stuff and it works flawlessly.
I prefer wireless mess because it does a "hand-off" as you move from device to device throughout an office or home. Wireless gear is improving all the time and a much faster rate than other hardware currently. I wouldn't read too much into the spec and "new" features. Wireless AC is good enough. Dont bother with "N", that's old news.

For routers, we have deployed the Cisco RV series for small businesses. They are a good buy and they have a lot of different models to choose from.
