I like the AB in the GB
+1. I've worked with USG, UniFi APs, UniFi Switches, and EdgeSwitches. Nothing locked out needing to pay for. The very slight annoyance with the UniFi line is requiring a controller somewhere (or a cloudkey) to manage the products. Absolutely no web interface on the local UniFi devices. Use the Edge products if you do not want cloud controlled devices. UBNT has a paid online cloud controller service that has some perks, but not really worth it for me or my clients.
I went with a cloudkey for simplicity.
