Bambino and Rearz are more absorbent. I was actually impressed recently with the Tykables Camies and LittleRawr. They have come a long way from where they had started. I would put Trest at the top of my list but they are currently out of stock.
I think one of the biggest flaws is they stretch with extended wear.. like overnight resulting in them being less secure and leaking. Also as Ohmo had mentioned press out leaks are an issue.
