Okay so I use a few different covers and diapers I use as covers.

Flips

Diaper safari

Econobum

Grovia

Applecheeks

Blueberry (although, i don't have a picture for you right now, its dirty... haha no one wants to see that)

Flips:

Ribbet (the green) and Twlight (the light blue) are the two that I have.

- Favorite things about them: I do like the BG look, and the PUL is usually really good. I've never had a problem with leaking. They hold well over night. Which is nice.  - Least favorite things about them: The price, I think for the quality and as many problems as people have they are WAY too much. The flap is crap, it doesn't hold anything in place. Might as well not even have it. THE ELASTICS. Ugh. So much hate. BG's already have a high chance of having relaxed elastics. Flips (and NBGE) already come with looser elastics. I wish I had a new flip to show you next to a 4.0 (irwin) ... actually.. a NBGE (jules) will do.. 

Both of these haven't been used too too much, the elastics are the exact same as what i bought them at. The NBGE fits exactly like a new Flip. So you can see the difference in elastics.  - Fit: Its okay, i usually get leg gaps, but thats because the elastics suck. I don't get leaks with the leg gap though, so thats fine.  - My rating for them: Out of the 6 that I use, I would place them in 6th place. They will NOT be able to be used for a smaller/next baby without being replaced. 

Diaper Safari 

Water (Blue) and Steel (Gray)

- Favorite thing about them: The quality is fantastic, the price is perfect (1/3 of the cost of Flips) The elastics hold up WAY WAY better than Flips. Their colors are really pretty. They have the BEST purple (its in the wash) The flip to hold inserts in place is PERFECT. It is just the right size. I never have my prefold/insert move around  - Least favorite thing about them: If a child has a PUL allergy, probably wouldn't be the best. Also, I would like to see some prints and patterns but whatever. haha - Fit: Like a glove. hugs tight to the skin, but doesn't leave marks. Also has TON's of growing room.  - My rating for them: This is my number 1 out of the 6 I use. 

Econobum

To save typing and time, they are the exact same as the Flip. However, I'll rate them in 5th place, because without the top flap thing i think they actually fit better than the flips. 

Grovia

Pudge

- Favorite thing about them: The prints and the fit! its amazing trim. The fit is one of my favorites of all time.  - Least favorite thing about them: I wouldn't hate them to be a BIT wider, so it would hold a prefold. Like it holds it, but it doesnt encompass it, you know? so I'm not too sure it would fit well. I'll try later to see how well it fits because I've never actually tried it ON the babe. - fit: wonderfully. Super trim. TONS of room to grow.  - My rating for them: 4th place. Only because its too trim to fit my size prefold... ahaha Which isn't a bad thing at all. Its a GREAT day time cover and swim diaper! I use it with FST and CBI and its PERFECT. 

Applecheeks

Wingin' It

- Favorite thing about them: I love that they can be used for covers or you can use it like a pocket. Prints are awesome. I love that if you use it as a pocket, the insert comes out in the wash. No unstuffing. Easiest diaper ever to put on. Fits great over a fitted, holds prefolds great. - Least favorite thing about them: The price.. and I hate that you don't get an insert with it. For price, i think you should.  - Fit: GREAT.  - My rating for them: day time my rating is number 2. Night time, my rating is number 3, because i haven't tried them during the night. 

Blueberry

Like I said, mines in the laundry pile, so no picture. BUT I do not use the cover. I actually use the Pocket diaper as a cover and I LOVE IT!!!

( I don't use the cover because its DG and I do NOT like DG) 

- Favorite thing about them: The prints are super cute, I like that the pocket is big enough to stuff in a prefold NO problem, or to even lay it on time. I like that you can use it as both a cover and a pocket. - Least favorite thing about them: Bulky. They are wide and bulky. it doesn't bother me, but for someone who cares about bulk that would probably ruin it for them.  - Fit: really nice! even though its wide it has a really great fit. - My rating for them: 2 for night time, and 3 for day time. Although really its really hard to decided that. Between applecheeks and blueberry i really love them both. Both as covers and as pockets. 

OH! I did forget one cover i've tried before.
