Cloth or Disposable diapers? Disposable for sure. I have tried cloth several times and it's just not for me.
Cloth-Backed or Plastic-Backed? Plastic backed.
White, Blue or Pink? As someone else said, if any color purple. Very sad to see Molicare turn blue.
Plain or Printed Designs? Printed, but not in the way most people seem to want. I actually like the medical style printing. I really like the print designs of Abena, Molicare, and Tena but they're not the best in terms of quality. I wish someone like Rearz or ABU made diapers with medical style printing and the same level of quality.
Scented or Non-Scented? Non-scented mostly just because anything I've ever worn scented burned my crazy sensitive skin.
Tape-Style or Pull-Up Style? Tabbed, I have zero interest in pullups.
