Which do/would you buy, battery or free range eggs? (the battery ones are cheaper)

I've never bought eggs before because we have chickens at home and yesterday I bought eggs and I got the battery ones and now I feel dirty. I don't know why I got them because I wanted to get the free range ones and they were only a dollar more but I was in a hurry and for some reason I still ended up getting the batteries. From now on it's just free range though.

Ok answer the question now.
