I agree. With our own experience, I found Moab fixing many of Maui's bugs.
I came to my own conclusion that Maui was just a stepping stone to Moab. You use the free Maui product which kind-of-works, get hooked using it but when you get down to serious implementation and need a scheduler that actually works, Maui fails in strange weird ways, HOWEVER you can easily "fix" the bugs in Maui by moving to Moab with very little effort. What a coincidence!
