Bows are powerful because they store the energy that is drawn backwards. This is different for compound and recurve bows. Crossbows that recurve are similar to traditional hand-drawn bows can be used as well. The string is pulled back, causing the bow's two limbs to bend. This generates energy. The energy from the string is released and the bow shoots. Compound crossbows don't use linear force. Instead, they make use of a combination of strings and wheels (cam-system) that pull back the string and bend it. This system allows them to produce more force, fire arrows faster than recurvebows and can generate more power. They are less maintenance-intensive than recurve crossbows, which only have a few moving parts. It's up to you which type of bow is best for your needs. If you want maximum speed and power, however, compound bows may be the best choice.
