I generally like plain white with no markings at all, but the crinklz, little pawz, and teddy I see as exceptions to that rule
The princess, idyl, spoiled, bellisimo, lavender, and classico are "over the top" and I won't be reordering. A lot of the others I consider "tolerable", like the safari, kitten, and SDK.
The teddy are the only example where I prefer the "lightweight" print over the white. My personal favorite all-white is the confidry, with the abu simple a close-second. IMHO those two are the best plain whites available right now and are definitely what I would have loved to have gotten my hands on years ago.
Plain white, particularly without wetness indicators are my ideal notion of a diaper. However, prints can be fun as well, so I'm happy either way. I like having a variety to suit my preference at the time.
