Their LTS pricing doesn't work for small businesses, but the rolling release might be an option for home use. Have you ever looked at VyOS ( )? IIRC EdgeOS was a fork of Vyatta and Vyatta became VyOS. Speaking of cards, I went with Compex WLE1216V5-20, which have an Atheros chip and are thus much better supported on Linux than Broadcom, etc. Right now I'm sticking with WiFi 5 because of the costs, but in the future upgrading to 6E would just be a matter of changing the cards (assuming they're supported by the OS). The other benefit is that you're free to upgrade your hardware as needed, which particularly for WiFi cards is great to have. Given Ubiquiti's and Netgate's recently hostile actions towards users and open source, this provides a great peace of mind.

The major benefit of this setup is that you don't depend on some manufacturer for updates. All will probably be running OpenWrt, though if that's too limiting / buggy, I'll just use plain Linux or OpenBSD on them. I'm currently in the process of moving my home network from Ubiquiti to an open solution with a few Mikrotik RBM11Gs to serve as APs, and will probably also replace my Netgate SG-3100 with pfSense with likely a PC Engines machine.
