I had a X-52 Pro and went to an all CH HOTAS setup. I just love the CH Fighterstick it is amazing compared to the X-52 Pro. The range of motion is very big allowing you to delicately control your aircraft with precise movements.
Although I have not tried the X-55, any CH products gets a big tick from me.
A lack of visual damage on all DCS aircraft is a big drawback I have noticed coming from other flight games/simulators. In IL-2 1946 if you hit an aileron enough, the aileron would come off etc...
