Different experience on PC than on PS4?

hey. I played on on the PS4 from the release on and stopped about 6 years ago.

I never endorsed an agressive gameplay and ended up beeing a quite average player with a postitive K/D when i lost interest and quit after a couple of hundred hours.

recently i started playing on PC and i find the gameplay waaay more competitive and challenging than on the PS.

i always end up in rounds with heavy unbalanced player numbers with me on the outnumbered side. 4 out of 5 games.

i know the games is quite old and many players are maxxed out and packed with thousands of hours experience but i find myself struggling even against low-level players (i know this can be experienced players with just a new profile; just like me). there happen to be rounds where i can hardly get 5 kills, even 0!

So, is it really THAT diffenrent on PC, or me just getting old after 5 years not playing and having slow reaction time?
