I use cloth, but my baby is a very, very heavy wetter -- so disposables work better at night. I've been using Luvs for a month or so without any leaks. (I like Pampers, but decided they're too expensive.)
Luvs worked fine for my oldest, too, who was also mostly a cloth baby. He had a very, very sensitive bum, and he got rashes with most disposable diapers -- but the Luvs were OK.
I do think they have kind of a funny smell. And I wish they had elastic in the back. But they work just fine, and they fit both my babies -- one was skinny and the other's chubby.
