Yeah they're good now. In the early days they had a lot of quirks and also a lot of people weren't settling them up correctly so older support posts have a lot of negative guff. But with their new setup and support apps (Unifi+wifiman) the success rate of getting things working how you want for a first timer is much higher these days.
Their new policy VPN routing and DNS filtering options in the ultra and max units makes the loss of full x-sense control less of an issue.
I used to have 2 gateways one pfsense VM and one physical to sort out filtering and stuff but I switched to ubiquiti and it does everything I need in one easy to manage unit again.
I don't think Ukraine will ever surrender. They may lose the war officially and Russia take over the government buildings but it's not a video game. The population will never forget with an unstable region for decades afterwards. We westerners can learn to accept a shitty situation if it's the only way to have peace. I don't think Ukraine will, they're built different.
