Worse for trials*, better for spins, bunnyhops etc.
* I know bunnyhops etc are trials, but you know what I mean, get off my back man, jeez.

No one can really tell you because you may be tall and feel more comfortable with a longer stem, it may not suit your bike or riding style etc etc.
So don't blame me if you try it and you can't make it work.
