Quest 3 for PCVR beginner? Or get a more expensive one?

I keep hearing about how The Quest 3 is great for beginners etc. But i have a really nice PC and want to use VR for sitting down and immersin or simulators. not shooting and running and moving around etc. I then hear that the Quest 3 isnt great for PCVR and its more a standalone system. I was thinking about one of the Pixmas or the BSB2e? opinions? it would be mainly for Flight Sim and racing Sims and games where you jsut look around in beautiful sceneries like you are there. Im not sure if that makes senseat all but yea
