I have Google Wifi at home and a unifi mesh at my office. Unless you are covering a massive area or have more than 25 clients, I’d have a real hard time recommending unifi. It requires much more configuration and maintenance. Google WiFi you really just forget about it - handles patches automatically, finds you the best channel automatically, tests your uplink daily and logs results.
Unifi’s software is much better than any other enterprise solution, but it still has a lot of rough edges and bugs if you’re doing anything non-standard.
