FuzziBunz, Rumparooz, Blueberry, Go Green.

I have two of the FuzziBunz and several of the blueberry diapers. I really like them both! The FuzziBunz have adjustable elastic at the back of the waist and on each leg. They're the only diaper that I've found that has that feature. They don't have crossover snaps though. For my itty bitty daughter, that made a huge difference. I've never had a blow out or a leak on my FuzziBunz. I like to pair them with a hemp Joey Bunz insert from Baby Kicks USA. It's so thin and trim, but really absorbs.
The Blueberry diapers that I have are second hand, but they're still in excellent condition. The elastic has lasted through 3 kids (2 of my friends and 1 of mine). I love the Minky diapers in the summer time. Mostly just because they are super cute to see under a dress :D Their one size combination inserts are awesome too! they are really really absorbant. I use them a lot for naptime. I have found that the Blueberry diapers are bulkier than my FuzziBunz.
I've heard really good things about Rumaprooz too. I just haven't had the chance to try them.
Never heard of Go Green.
My personal favorites are Baby Kicks 3G with the hemp insert. They are really trim and the fleece leg gussets don't leave red marks like some other diapers do.
You should look for a clothdiaper store that offers a trial program. That way you can try a little bit of everything to see what you like.
If you are sold on the 4 brands that you've mentioned, I would just go ahead and order one or two of each kind. I've noticed that some diapers that fit really well when my daughter was an infant, don't fit so well now. I've also noticed that some diapers that didn't fit when she was an infant, fit fantastic now. So, just because a diaper doesn't work for you right now, doesn't mean it won't 6 months down the road.
I don't know how old your child is, but one size pocket diapers often don't fit when the baby is first born.
Please message me if you have any other questions regarding cloth :D

The only brand I have used from your selection is FunzziBunz. They are fantastic...I've used the same set for two babies and plan to use them again for #3 (so they are long lasting), never had a blow out or bad leak and I used them for a girl and a boy...They seem to be very comfortable...both of mine wore them well into toddlerhood (2+ yrs) and they never complained that the diaper "hurt" their legs like a few other cloth diapers I used. I don't think the others actually hurt, they never left marks, but they could be stiff when you first put them on...never an issue with FB. I did a really stupid thing with mine and used diaper rash cream when my daughter had to take antibiotics and didn't use a diaper liner..then I had to go through the trouble of stripping the fleece and it honestly never really got it back to normal, so whatever cloth diaper you decide on, invest in good diaper liners if you need to use rash cream...

Try 1-2 of each then decide:) All diapers fit differently on different babies. Before buying a full stash of any one diaper, try it so you know it fits and that you really like it. There were a couple diapers I thought I would LOVE but ended up not liking them at all. I haven't tried any of those brands, but a friend of mine like Fuzzibunz and Rumparooz. I've heard great things about Blueberry. Haven't heard anything about Go Green.

Message me if you have any questions related to CD's, I'm more than happy to help!

Fuzzi Bunz are a great diaper. I LOVED ours...but that was when they had sized diapers. I have not been a huge fan of the one size with the leg elastic because they just don't give a good fit. Also, the diaper is HUGE in the crotch on the smaller settings. Blueberry I don't care for. They have awful customer service, their products are far over priced and they fall apart very quickly. The last 2, Rumparooz and GoGreen are interesting. The Rumparooz are one of the best diapers on the market, you can not go wrong with them. They are a great diaper, fit well and function the best out of any diaper on the market because of their inner gussets. Their customer service is also the best I have dealt with, by far. GoGreen on the other hand is a fairly new brand and has copied the Rumparooz and is now selling their "GoGreen" diapers at knock-off prices. Its really REALLY sad and disappointing to see one WAHM do that to another. I would never buy a GoGreen and I will never recommend that anyone else either. The GoGreen lady actually lives in the same city as the Rumparooz WAHM. How disgraceful. If you want to see a very cute story, that will make you cry (and if you haven't seen it already) watch the video about how the Rumparooz where "born" :) http://www.youtube.com/watch?v=tssMUV9AuJY

As for inserts, the Rumparooz 6r soakers are an awesome insert and they will fit in any pocket diaper that you have. They also come in hemp which is great. If you to use the hemp and microfiber together you can do that too as the pieces are interchangeable.
