HP Reverb G2 is going for $400, seems tempting but everyone shits on it's motion tracking pretty hard.

I'm looking for a decent set for PCVR, got ~$600-800 to burn but there doesn't seem to be anything in that range.
Is the Pico 4 good? I know it's a standalone but apparently it runs pretty well with Virtual Desktop and it's ~$350 (If I buy it during my trip to Japan)
