Been using an x52 Pro for over 2 years now. Great feel and look, and plenty of buttons, particularly if you can supplement some commands with Voice Attack or other input devices.
Only issue I've had is some minor pitch and roll drifting, which I've fixed with a joystick curve rather than adjusting the dead zone. This has worked out well because the curve I was going to use in any case solved that problem. I did the magnet mod to increase the movement precision of the stick, and that has made a noticeable improvement. I also bought the 3D printed discs that can be used to increase the tension.
Main gripe for me has been the lack of center detent on the throttle. It comes with 25 and 75 detents, which I did the mod to remove because they're annoying, and I don't play non-space flight sims. I don't want to use the reverse button, so I really want a throttle with a center detent so I know when I'm at zero without going into reverse first, which is harder to do in VR. So, I've been eyeing the VPC Constellation Alpha stick with the WarBRD base and their MongoosT-50CM3 throttle. Not been able to justify it yet, but I hear mostly good things, so...
Not considering the Warthog because the stick has no yaw, and I don't want to use pedals.
