I've been doing cloth for 4 months now, and what I would have done differently than what I did do is order several different brands to try, then order up the ones I like best for the main part of my stash.
I'm liking the pockets the best, and have most of those. I do have some fitted's also (the kind you use a cover on), and would like more of them as I find they go the longest when we're out. I have some AIO's as well, MonkeyDoodlez, but I don't love them as they're more bulky, and take forever to dry. Hubby heads for those ones first though.... but he's not the one doing the laundry! I like my fleece AIO's, as they're so soft and cuddly, and dry faster, but generally have to pop an insert on top to make them go long enough to not be annoying.
