Firstly, I must admit that I haven't tried very many other brands of diapers since using Pampers. I tried White Cloud and Luvs in the past. The White Cloud diapers were not the quality of Pampers and had to be changed much more frequently. The Luvs diapers were ill fitting for my daughter and I ended up seeing baby butt crack when she was walking about.
I am absolutely happy with Pampers. They absorb really well and can hold a lot. My daughter has fallen asleep early in the evening and made it through a 12 hour night easily without the diaper breaking down. They wick away the fluid and leave her sensitive baby skin looking perfect.
My daughter is kind of small and Pampers provides the perfect fit. The legs are gathered and stay close to her skin. We have only suffered from leakage a couple of times in 17 months.
The price of Pampers is generally higher than other diapers. I have rarely been without a coupon though, helping balance out the cost. I just can't sacrifice the quality for a cheaper product. And Pampers has a great perks program allowing people to build up points for fun baby and toddler product purchases.
