We love the aplix for a lot of the reason the other mamas mentioned. We also REALLY like the side aplix, but it's hard to find dipes with that. We have mostly aplix with some side snapping, and very few, if any front snapping.
I love side aplix too! I have both on my site but snaps seem to sell better so I make snaps for instock. For our dipes I make side aplix.
