PC players don't have any benefit over console players in this game. I do just as well playing on Xbox One X as I do on the PC, no matter if I use a HOTAS or a gamepad on either (that said, I do very poorly when using keyboard and mouse, however). My friends that play excusively on PS4 Pro and Xbox are usually doing very well, too, on their own or flying on my wing.
The only thing that I could imagine may have a little bit of an advantage is playing in Virtual Reality, be it on the PC or on PSVR (sadly, Xbox doesn't support VR so far), but I can't confirm since I don't have a VR headset yet, as you'll be able to look around (hopefully Track IR support will be added at a later date so non-VR users can also experience this) and be more immersed in general.
Most of my random matches have 1-2 PC players, while the rest are on consoles. I'm in central Europe as well.
I never abandon any matches either, even if we happen to get shredded. Defeats are a valuable lesson that one can learn from and get better. If you always quit out of hopeless matches, you'll never get better.
By the way, if you only want to play with like-minded Playstation players, you can always turn crossplay off.
That said, perhaps if you'd have spent the time you've use to spit venom at PC players in these forums to practice and actually become better at the game, you might see that it's all about player skill, teamwork, knowledge of the game and - to an extent - connection quality and not which platform they play on. Or maybe the game just isn't for you.
