Crossbow: More power than Bow but harder to load.
twice as accurate as a bow even an infant could hit the target, infact it's more accurate than most guns in my experiance.(Exageration)
Bow: amuniton is harder to make but easier to find after firing,
the bow is also easier to packdown and is far more compact than a crossbow but is worse in close quaters.
I've fired both and have yet to see a Bow that you can use in Hand to hand... please... tell me where you got this information so i can brutally murder the moron who told you all the wrong information.
I think bow are easier to use by anyone who are familiar with it or happen to used it before... But crossbow are pretty complicated in use (except the automatic crossbow). Anyway, both of these weapons would give difficulties to the beginner users... I would prefer bow cause I used to practice for archery on High School... :)
