When I asked that question not long ago on the rise of flight forums most people said the thrustmaster t16000m.
On the outside it don't look that nice and looks boring, but on the inside is it has them hall sensors like the x52 joystick.
It's very nice and easy to use.
the button are okish but never had a problem with them and you get 6 on each side + the others on the stick :)
I could of got the x52 brand new cheap but because the t16000m is good anyways I did not feel the need to pay extra.
But the x52 throttle would of been nice :)
