First hand experience many times over: there is little more regrettable than placing Ubiquitis latest test-it-in-prod release in to an Enterprise setting.
Proxmox's record in 2025 wasn't particularly great but it's a hell of a lot better than Ubiquiti's. And before someone starts complaining that it's not a fair comparison because Ubiquiti has so many more products: they have a unified OS and management tools. They also have orders of magnitude more revenue and can afford far more in engineering resources.
I mean it's all prosumer grade stuff. I get hassled at work to sell their network gear over Cisco and Aruba because of the price but it's a flashy and cheap.
