Earlier quoted context omitted.
As far as I understand, 5ghz is weak on distance which is a problem at my apartment building. Every time I'm on the 5G SSID, the internet becomes unusable in the bedroom and kitchen which makes 5G unusable for me because my devices don't select the 2.4ghz band automatically.
I'm a little late with my reply, but I wanted the solution to be here as well. Poor 5ghz propagation solved: https://eero.com/ https://lumahome.com/ https://madeby.google.com/wifi/how-it-works/ http://www.samsung.com/us/smart-home/ https://www.open-mesh.com/
Mesh networks are definitely cool but the biggest downside is that they are a bit pricy and I have heard that some of them do not work well. I cannot speak for any of those which you provided, though, except google which works well supposedly.
