I've had a Thrustmaster T16000M which I find very comfortable to use, but the usual issues with the rudder axis are a big problem.
Recently tried a Raptor Mach 2, which is very nice but I find it less comfortable than the T16000M. A really annoying feature on the Raptor Mach 2 is a button at the bottom of the stick, which is easy to accidently press with your little finger. This button does nothing useful and can't be assigned to anything, but if you accidently press it when gripping the stick, it prevents the guns from firing.
I purchased the Raptor as I was frustrated with the rudder issues on the Thrustmaster. Interestingly though, since I set up the Raptor, the Thrustmaster rudder axis has been fine, so I'm no longer convinced that the rudder problems are entirely caused by the potentiometer.
