I bought the snap on set when I was in school. Years later I wish I would have used the money elsewere. The Martin hammers are better quality, but really you use the cross peen and chisel will be the hammers you use 9.5 times out of 10. You can spend a lot of money on hammers and dollies but really there is only a couple you'll use everyday in the body shop now and again the others will come in handy but unless your going into a metal shaping shop I'd get the nessities and save money for other things. Al long as your hammers are fored you can always clean up shape and polish the surface and an atd 40$$ set would do great. The better hammers are just more comfy in your hand. I like snap-on but won't spend another dime on it.
