out of those choices your best bet is going to be the Pop-in. They're our main nappy, and the dream dri insert bits are dry within 30min of coming out of the washing machine, and the outers in a few hours. I like BumGenius too, but out of the 2 would say the pop-in is a better nappy as it has better leg gussets, and 1 extra row of poppers to adjust fit, and works better on newborns than a BG, also doesn't leak as much with toddlers (we had lots of issues with BG from about 17 months, hence the switch to the pop-in)
I would say to get the main bulk of your stash in BG or Pop-in, and maybe 1 or 2 "fun" nappies that would take a little longer to dry (like the itti, Fuzzis, Real Easy...) just to mix it up a bit.
