I've never had a problem with hickory handle ball peins, until I used deadblow ones. They deffinitly hit harder, and you get a bit more control if you're doing delicate driving work (such as un-seating bushings inside Hydraulic Cylinder Heads where you musn't damage the bore where the new bushing will sit). I've used the Snap-On's and the Armstrongs and I'd say they have one major difference. The Snap-On is very **** looking for a hammer, and they come in different colours if you want to be stylish and have a nice looking Hammer Drawer... other than that there really isn't a point. The poly wrap around the snap-on's head is quite a bit thicker than the armstong ones my shop has, but they both hold up extremly well under heavy use.
