How can you even compare the 2, gun hunting is a million times more easy,(and i do both) you have asight on a gun( zooms in), you can be perfectly steady,you can shoot alot alot further with it, they cant jump the string, you can use the wrong pin with a bow, with a bow they can see you pull it back and get scared, you flinch slightly with a bow, you miss alot more than with a gun, if its to windy its hard to shot with a bow, You usally have to stand to shoot with a bow, the deer has to be alot closer so the deer can smell you.
Just to name a few.
