Your decision depends on what you actually want in terms of thickness, ease of use, laundering, and a few other things.
You have All In Ones that are a one piece garment that are the most like disposables. They are designed just like disposables for ease of use, but they tend to not last as long, the waterproof lining will not last as long as the padding, can take longer to launder, and it's more difficult to get rid of odors. More than likely, you will need plastic pants because most of these have compassion leaks and they aren't designed like disposables regarding leg gatherers and leak guards and the material is sewn on top of the leak proof lining without a barrier system. You can only as so much extra padding before it leaves you diaper prone to leaks.
Pocket diapers are like All In One diapers, but they the bulk of the padding in a separate pad that you stuff in between the linings. It's easier to launder these, easier to get rid of odors, it's still pretty easy to apply. You will still be prone to the same leaks above and have less coverage area.
Prefolds and Plastic Pants are the original way of cloth diapering. It's the most customizable way of diapering. You can choose the thickness, colors, fabric of padding. You can choose different plastic pants colors, materials, height, width, style, and much more. There's easier ways other than pins to apply the diapers. The only cons to these is that it could take longer to put on. As I said though, products such as Snappi Fasteners, Boingo Fasteners, and others that make it a lot easier to put on.
Before you buy any of these products, I would suggest investing in a fabric tape measurer to ensure your purchase will be right for you, and actually fit you. These are pretty cheap and can be found in Wal-Mart or other fabric stores. This way you won't waste money.
