Typing this on my T420 running OpenBSD. It does everything I really need it to do. I don't play (new) games, and I have a more powerful server tucked away here in case I have any CPU-intensive jobs I need done.
Honestly after seeing the absolute state of Linux on the desktop over the last decade, there is no reason for me to even consider it any more.
Can't comment for all aspects of a Linux desktop versus an OpenBSD desktop, but one example that comes to mind is the sound system. Just try reading the design paper of sndio [1]. It is a pure joy to read. A beautiful architecture.
Now compare that with ALSA / PulseAudio / JACK / PipeWire... The audio system in Linux is fragmented and incomprehensible.
