I'm in love with the STLE, and I own (and moving) the Xmen LE, so I can be a little biased. I love video game/pinball, so I should love WOZ, but the slowness (and the mirage LED effect) kinda kills it for me. I rate it higher than an XMen LE, not for the gameplay, but rather for the wow factor. I appreciate it, but doesn't mean that I would want to play it more than the others.
WOZ = Slower gameplay, but FEATURE packed.
ST = Fastest, extreme speed, open shots.
XM pro = 2nd fastest, tighter shots
XM-LE = Slower with more features than the pro
