Switching to Ubiquiti, from high-end Asus gear, has been awesome. Everything just works. Networking is now a non-issue, and when my wife tells me the "internet isn't working", I can respond, "it's not my fault!"
That's worth the cost to me.
I heard some horror stories with new ubiquiti gear, but my ERPoE router has been serving me gbit and PoE for AP since 2016 and 0 issues, it even handles WireGuard using some hoops.
I've been meaning to give out different DNS servers via DHCP on the guest network vs the internal but I just can't face trying to configure that thing again.
I'm glad you're happy with yours but replacing mine with Mikrotik kit is super high on my home-network todo list.
Retrospectively I think the ubiquiti AP’s flakiness was caused by a firmware update. This Reddit post is ~2 years old:

I’ve been meaning to do a hard reset and/or change the firmware, and put the ubiquiti AP back into service, but the old & slow ddwrt router works fine for everything not an Ethernet cable.
