I used CH for almost 10 years, they are built to last. I had a X-45, that lasted all but 6 months before it started getting center play. CH can be used for anything and it can be programmed to do anything. I would probably still have CH but I wanted a better feel and the warthog was a great fit for me. You can buy all 3 CH (stick, throttle and pedals) for about $300-330 in the US. I used my CH for Lock on, FC 1,2 and 3, DCS A-10C, DCS BS, Arma and BMS. I had zero problems and still have all my old profiles just in case I ever switch back to CH.
I have not seen or used the X-55 in person, so it could be a great HOTAS. I hate the twist rudder and I have heard a few buttons could of been placed better.
Make sure you do some good research about both products before you buy.
