For single core performance, Intel is still king (if going for high end consumer CPU at least). So if you care a lot about high refresh rates and so on, go Intel. But at the moment, it just isn't a terribly great deal. I am extremely pleased with how my 3900x is performing. I got it semi late, due to shortage, so I dont know how it was before the bios updates, apparently it was a bit rough. But works well now, even if it struggles to get advertised clocks most of the time.
Dont think I ever before had a computer with AMD cpu, maybe the very first family pc we had. Well had ATI cards, but before AMD takeover. Quite happy with the switch to AMD from Intel now
