Cloth for me. Cheaper for me in the long run, and I want to have more children, not just one. Easy to put on. No scraping of the poo in the toilet (breastfed poo is water soluble, and after you start weaning you just lift the poo out on a liner and flush that). No chemicals on the baby. And (this is my speculation only, no idea if there's any proof), no risk of long-term damage from gels in disposables. I don't put stuff like that near my foo foo, and I'm not willing to risk it with my baby. Control over absorbency (esp. with pockets, or adding boosters). Fewer leaks. Cloth nappies are also pretty, and it's fun to choose what you want to put on the little bum. I don't mind washing, I line dry, and I enjoy folding and stuffing nappies (need a life, I know). I don't like the long decomposition time disposables have, and the chemical smell of a wet disposable.
That said, it's your decision and whichever you choose, no one should judge you.
For info, google The Nappy Lady, she's got a lot of information. Go to Natural Parenting section and have a look around; Rachel_C has a blog and she knows heaps about nappies, environment, costs, etc.; Little Pants has a nappy library.
Don't close your mind to anything, and don't let anyone mock or manipulate you into something you're not comfortable with (this goes for both sides).
