I have the Nighthawk and I think the bombs are a bit stronger. With that vehicle, they really do go hand-in-hand but if I had to pick one weapon I'd go with the bombs. They're powerful, reliable, and don't have a clunky locking mechanic. You'll usually do 80 damage to each player so you won't be killing anybody with it, but it'll quickly give you the upper hand in a fight and you can easily finish what your teammates have started.
