Mommas - what diapers are your favorite?!

We all the sudden have leak issues and I want to know your favorites! For the whole first year of my son's life, he has worn pampers. We started with swaddles and then went to baby dry. He is a big baby: 13 months old and 27lb/ 31.5" tall. He has worn a size 6 for about 2 months now. But all the sudden he wakes up wet every morning. I thought maybe since he was thinning out a bit (just started walking) we needed to try sizing down. I did that, and he still leaked. Any suggestions?!
