We are all using Unifi stuff because there are no alternatives.
Of course it all depends on which bits of the Unifi ecosystem you are using. If you just want a singular device like a firewall or a WiFi AP, you can find alternatives.
But for the full stack from firewall to switches to APs, there just isn't anything that integrates as well as Unifi gear.
I have have lanner tech router that I installed a as internet gateway. I have been very happy with it. Works well, lower power, small has multiple ports. Can use SSD for storage.
One must install the OS; whether that is OpenWRT, OpenBSD or whatever OS. This means that one needs to be quite familiar with the OS install. So, one probably needs to be a technical person. The one I got had x64 intel based CPU, so it should run just about any linux or BSD distribution. The one that I got has a serial port for the console (no VGA, HDMI, display port etc).
Aruba Instant On. It's Aruba's enterprise hardware with all knobs stripped and on a huge discount.
I suppose some people might find their use of a cloud based "controller" disagreeable, but I honestly think it's a plus — it's barely ever needed and it's one thing less to maintain.

Until your network gets pwned because the cloud controller gets breached.
