I love my Turris Omnia!
I got the one with the WiFi 6 card. The cool thing is that you can easily open it up and replace parts.
I run the upstream OpenWRT rather than the customized version by Turris. They are good about submitting patches upstream.
Part of it is the community. I really like the OpenWRT community, but it’s harder to engage with them when you run a downstream distribution.
But also I’m a bit of a hacker (in the traditional sense). I like to experiment with custom builds of OpenWRT. (And FWIW, their build system uses the same menuconfig as Linux.)
