Not a fan. Absolutely not.

They had multiple security incidents which they kept under the rugs for a long time, they have the tendency to EOL devices without warning (which then means you need to replace your sometimes 9month old device or your whole enviroment can’t be updated), their lock-in into their ecosystem is much more complete as they can’t be used properly without their enviroment.(e.g. Omada devices can work without the Omada stuff, with Unifi you will always need a controller for some functions).

So if you realy need SDN features like Unifi look at Omada,otherwise Mikrotik is a solid alternative. (And OPNsense for firewall)
