Love mine (09 GF Paragon upgraded to 10 speed). It’s great for local riding (South Downs); balanced, easy to hop over obstacles, fun in the woody singletrack and on average over 1mph faster on my regular loop than my 26in FS, but if I were going to Wales, for example, I’d still take the FS every time.
You’re gonna have to try one before you know the answer in your case.
