I think my current favorite diaper is the FuzziBunz. I am lucky to have two now, and I like the adjustment at the legs. I am not always a fan of having to snap 6 snaps to put them on my wiggly little one, but they are the only ones that don't have a little gap around the legs once he is on the move. He is 11 months old, and has been walking for over a month (10 months 1 day is when he started). I have to make the other diapers too short in the rise to get a good seal in the legs. As a result, once he moves a bunch, either there is an issue at the top or they are sliding down a little. Luckily he isn't a heavy wetter, so the only time we get leaks is over night (if he nurses a ton). But, I don't have any of those problems with the FuzziBunz.
But, they aren't the easiest to stuff. They are the narrowest, so it is often hard to stuff two inserts through the middle. I get it done, but it isn't fun. But, the thinness is better for my little guy - his hips aren't pushed out as much.
Oh, the compromises when it comes to diapers! I wish I was a better sewer so I could make my own! Leg elastic like FuzziBunz, open at the front like TweedleBugs (and Thirsties Duo which I haven't tried yet), and options for velcro, two snaps, and three snaps!
