batting is not very good you have gaps where pipes and wires are.
Now on your attic it is the same except the foam is sprayed up top in rafters meaning you have to heat and cool your entire attic but it is a full seal. This is suppose to be the best. Its very high though. and I still have my doubts because you are doubling how much you are cooling and heating. You can't go wrong either way. just try to steer away from batting it will cost you in the long run.
also if you go cellulose direction there are different kinds make sure you hire a professional because the cheaper brands will eventually settle if not installed properly.
hope this answers your questions

Yes sir. Thank you very much. I'm not sure who is doing my insulation yet. The guy framing my house is supposed to hook me up with a guy this week and I'm going to see what his recommendations are. Insulation is one of those things I do not mind spending money on. The guy framing my house built his own house and he took me over there to climb around in his attic so I could see his and he had the foam. I think my old house had the cellulose. It looked like regular insulation but sprayed. It was pink. I didn't like that because every time I went up there my allergies went crazy.
