We use cloth diapers at home, but disposable when we're travelling or out and about. I never wanted to spend more money on the expensive diapers, so I've always bought the store brands. My mother-in-law, on the other hand, always buys Pampers to keep at her house when we visit. In my opinion, the only thing that really makes Pampers better is the stretchiness of the tabs, better, Velcro, and pictures of Elmo, who my son can't get enough of. The Walmart brand has pretty stretchy tabs, but do seem to get more saturated overnight than the Target brand. We almost always get the Target brand, and they have served us well.
Good luck,
