We used them with DS, mostly motherease and tots bots cotton ones (used to be able to get a VERY good value pack of those on Amazon, but not sure whether it's still on there!). Also Blueberries are lovely but very expensive (they are pocket ones).
I really didn't find them that much hassle as long as you have the shaped ones - we started out with terries but I hated them as they are so hard to get on a wriggly baby without them all unfolding. That said, I still found washable ones a bit harder than disposables to get on once they get a bit older and more wriggly, as you have to keep the liner and nappy together and then put on the wrap, so need to keep them still for longer. Pocket styles are a bit easier for that though as no separate wrap, so only got to keep the liner and nappy together.
I did find clothies better at keeping in explosive new-baby poos than disposables, where it tends to all shoot up their back or out the leg every so often! If we ever had leaks with them it was usually just wee, so not nearly as messy. When they get onto solids and start doing more solid poos, that's when the papery liners really come into their own as you can just chuck the liner and most/all of the poo straight down the loo, and the nappies stay much cleaner.
My top tip is ALWAYS try before you buy lots, as different styles work for different babies - if they don't fit your particular baby well they will leak (this goes for disposables too btw, don't buy tons of one brand without trying a small pack first!).
I didn't find washing them all that much hassle when we just had DS, just bunged a load in the washer a couple times a week, no need to soak them or anything. Also it is easy enough to combine them with disposables if you want, e.g. we used disposables if travelling, and always at night as DS went through a phase of very heavy weeing and I never quite trusted the clothies to get him through the night!
We stopped using them when we moved house though, as we were living at MIL's for a bit and it was too much hassle. Then when we got the new house, never started again - 2 reasons, first was that we ended up setting up 2 separate changing areas (upstairs and downstairs) and didn't really have enough washable nappies/wraps/buckets to stock up 2 separate areas.
And the second big reason was that DD came along and I couldn't face the extra hassle once we had two kids (esp as I already seemed to have the washing machine on non-stop just dealing with their clothes, bedding etc never mind nappies!). DS is pretty much out of nappies now though and I occasionally toy with the idea of going back to washables just for DD.. but still a bit put off as I just have so much less time to deal with washing etc now we have two.
