if you're going for sound, i think the morley is better. IMO, of course.
if you're going for more specifications, get the ibanez. it has the auto off and the spring action mode. tonelok buttons so you can save your preferred settings.
based on looks, i like the weeping demon.
check out harmony central. i read somewhere that the WD7 is the highest rating wah in the website.
test both, of course! good luck!
