You have the PS4 pro, you can put an SSD in it and plug in KB/M.

The only difference is frame rates which is a crucial factor (for me at the very least), for example there was this fight in Omega that really killed the frame rate while on PC there are no issues (if you got the hardware for it) and soon they will bring back the unlimited frame rate option again so I can enjoy to play on my high refresh monitor again.

So yeah, makes not to much difference some people enjoy to play with sluggish frame rates, other people prefer to play with smooth frame rates (in the ranges of 144-200).

But ultimately it doesn't really matter though, having a 200Hz monitor won't really increase your DPS. I've seen bad people on both PS4 & PC and also seen good on both of these platforms.

Somebody in my static is on PS4 actually and she's just amazing.
