I've tried all those boards as well and totally agree that the Akai action is terrible! At least for a keyboardist. The springs are far too stiff and the black and white keys are very unbalanced (black keys are even stiffer than the whites). The 88 keys weighted version has a nice feel though.
The Edirol/Roland is a good board and pretty reliable but the keys aren't full size (no go for me), they are scaled slightly smaller than full size. Aside from that the feel is decent (I used to own a PCR-M50).
I went with the Axiom (older version). It has been abused on tons of gigs for 3 or 4 years now and is still holding up fine! It's missing some slider knobs and one is chipped, but they all still work. Even after I broke one of the encoders (still there but a little loose), it still works if you press while turning. The action is better than most others I've tried, but it's not without faults. The keys are a little spongy, but the biggest problem for me is that the black keys are much more sensitive than the white. Using the same physical velocity from white to black will trigger a much louder note on a black key. Once you get used to that, it's a nice board with a good feel and full size keys.
I'm still waiting for something better and reasonably priced

. No need for all that gimmicky automap crap here. You can configure that within the software and make a template; done.
