We have only been cloth diapering a couple months, but so far I have also been very happy with the All Free&Clear on our diapers. Both I and DD have very sensitive skin, and have been pretty happy with the various brands of the fragrance-free HE detergents, but this one is cheaper and I don't seem to need to use very much. I looked into some of the eco-friendly brands like Charlie's, etc. but I am really not organized enough to order it online nor do I feel like experimenting with yet another product right now. So I'd say, if you have the inclination try the Charlie's and compare it with the All Free & Clear. Good luck!
Oh, and I always wash in hot water unless it's a poop-free load (not often). I wash most of our clothes in hot water too unless it's a delicate item because dust mites freak me out.
