I think most people prefer whatever type they had as a kid.
I usually wear disposables. Historically I tend to go for plain white diapers, but the past few purchases I've made have been printed diapers. The printed diapers seem to be better quality overall, plus they're cute, so I might stick to printed diapers (plus, since I only wear diapers to bed, and since I rarely actually use them, one diaper can last me for a week - I get a lot of mileage for my dollar!).
