Both MegaMax and Crinklz are very good diapers, but also very different. I like both of them but for different reasons. To sum up the main differences, based on my opinion, are:
- Tapes. The tapes on MegaMaxxes adhere more strongly and stay in place better. I love MegaMax tapes.
- Graphics. Crinklz have some of the cutest graphics of any diaper while MegaMax only offer solid colors (and tie-dye).
- Capacity. MegaMaxxes have higher capacity.
- Thickness. Crinklz are relatively thin diapers (but swell nicely and hold a good amount for how thing they are).
- Sizing/fit. MegaMaxxes are sized much larger.
- Price. Crinklz are probably the best value when it comes to price per diaper and quality.
I think Crinklz shells are a bit Crinklier since they're thinner, but when it comes to thickness/bulkiness and capacity then MegaMax definitely has more of both (and MegaMaxxes landing zone can be pretty crinkly). Crinklz are really good if you want a cute babyish design and/or if you wear a lot/often since the cost savings are extremely good without much of a compromise on quality. Based on what you're looking for, namely the capacity and bulkiness, you'll probably prefer MegaMaxxes more, but Crinklz are definitely worth trying. And just because they're thinner and probably overall have less capacity, they swell a lot and really nicely and hold an amazing amount for how thin they are.
