If you shoot them in the head there is zero difference, have killed a ton of them with both. A air rifle is very effective if you can shoot and hit what your shooting at, chest shots even with .22 cal can result in them getting to a hole or hanging up in the tree.. best to take head shots always, just wait for a good shot, another good shot is underneath the chin thru the neck into spine.
If using .177 dont use hard cheap pellets like crosman as they expand very little better to get JSB Diablo pellets.
I agree on shooting owner in the Azz as the dog doesn't know they are in someones yard but usually the dumbazz neighbor does.
Rabbits are easy to kill can kill them with a daisy red ryder, fox squirrels are the water buffalo of small game they make a coyote look like a whimp when it comes to will to live if hit bad.
I agree completely with all of that.
