Two completely different bicycles. One that can go over rough terrain at high speed and yet remain in control. The other bicycle needs to maybe slow down some to do the very same terrain. At least until you get used to no rear suspension other than your legs. On a rigid bicycle you stand quite a bit more of the time than on a full suspension. The rigid tail will be rougher on you because you are the suspension. Sorry to hear you broke your wrist. Heal well.
