tbh I'm not entirely sure what hardware I'm looking for but I want it to have Wifi 6 (or 7) so that I can do stuff like streaming VR games from my gaming PC to some kind of VR headset (I don't own any atm because I refuse to buy Facebook's headset). It should perform well with 10+ people for LAN parties, etc, and overall be stable and performant in general. My other requirement is that I can install some kind of open source firmware on it so that I don't have a backdoored stock router OS that talks home to the producer (or CIA/NSA for that matter).

To me, it seems like the Turris Omnia has worse overall hardware specs than other routers such as the Flint 2 (GL_MT6000). I'm also not really locked to OpenWRT in any way, just seems like people really like it. I'll have to do more research on openwrt vs pfsense though..
