If you can fit in both fine, I would seriously recommend buying Depend Max Protection, however since I can not tell you which diaper to buy, I will explain the pros and cons of each choice.
Pros: Cute designs (for my sissy side), durable, easy to find in stores, inexpensive, makes a good stuffer, discreet.
Cons: No XXL size, limited containment (They only hold one medium wetting for me), not made for messing, very thin, cloth backing.
Depend Maximum Protection:
Pros: Plain white, no sizing issues, easy to find in U.S. stores, decent containment, decently thick, inexpensive, crinkly plastic backing, babyish feel.
Cons: Not as good as Bambino or Molicare (but is the best of the Depend product line), no cute designs, not super discreet.
I have tried both Depend Max Protection and Goodnites, and I truly enjoy the Depends much more. However, I believe you should base your decision on reviews of diapers and on the pros/cons I listed. I am currently working on a Depend Max Protection review which is not finished, but will be very helpful when it is.
Whichever diapers you decide to purchase, I hope you enjoy them, and I hoped my post helped.
