Sealer (from Giant) - my friend likes it, but was leaky on my baby
Pureen - leaky also
Drypers - hate the plastic tab. noisy to rip off and sticks to the baby's legs.
Pampers - works well, but the fit was so-so
Mamy Poko - fits my son the best and works well
I think every parent has his/her favourite. It really depends on the baby's size/shape for fit, and whether the baby's bum is sensitive or not. A matter of trial and error i guess coz every babe is different
