I like my ME OS. Same for the Airflow covers. They were the first diapers that I tried, and after trying a variety of other dipes, including Sugarpeas, fuzzibunz, happy heiny's, kissaluvs and more because I was just to curious not to, I have now gone back to mostly ME OS. It's the only dipe dh will reach for now, and he has tried them all also (even cpf's with snappi's and wraps). They are bulky on newborns (even my 10lb 10ouncer), but as a OS dipe, you should expect that. They are a good quality diaper, the fit is the best I've found on ds, and they wash well. I also think that they are very reasonably priced, but I'm from Canada, so I have to factor in the exchange, making a lot of WAHM dipes pretty expensive. The only thing about the OS dipes is that they aren't very absorbant and feel like a wet towel even after 1 pee. I add a fleece topped hemp doubler to mine now that DS is older and they work great. I also tried a Sandy's, and I honestly don't see that much of a difference in them, they are thicker, but not very much more absorbant, really, when you factor in buying 2 different sizes and paying more for each diaper. But again, it's about preference, and they are side snapping and the same quality as the OS, just a different option. I'd buy one of each before investing in a whole system.
The airflows are amazing at keeping leaks at bay. But they have left red marks on ds's thighs when they are on anything but the loosest setting. They are a generous fit and quality made. The prints aren't very good for the cuteness factor, but to me that's secondary to quality, and you are getting quality covers in the airflow. I also encourage you to take a trip on over to diaperpin.com and view the reviews. I've found that site very helpful.
