With the information you provided, it’s hard to answer definitively. But in general, a longer bow will be more forgiving and faster. The problem is that we don’t know what bows you have chosen.
For example, if one bow was a longbow and the other was a recurve, then that’s like comparing apples to oranges.
The best way to answer your question is to shoot both bows. Then you will know what is best for you. But remember speed isn’t everything. If the bow shoots really fast, but you aren’t accurate with it, then what’s the point? A super fast miss is still a miss.
I hope this vague answer helps. While I am giving vague advice, here’s a bit more… Don’t worry too much about your choice. Pick the bow that feels right in your gut and makes you happy. If it turns out to be a bad choice, then you can always remedy that with another bow. 8)
