I've heard great things about simplex. I have a few in my stash for the next baby. I'd steer clear of the grovias, they wick like crazy, if you are planning on the baby just wearing t-shirts they work just fine, but with onesies or pants they just don't work. Kissaluvs are great too, super easy to use.
