I own MM and WOZ (never seen or played TH). MM had always been my favorite game...until I got WOZ.
WOZ is a phenomenal machine. The rules are extremely deep and it's a stunner all around - display, lighting, sound, features, playability, fun factor, etc.
At about $8K for either MMR or WOZ (or even $9K WOZ), it's no contest. WOZ all the way. Every day.
And since this will be your ONLY machine, I'd HIGHLY recommend WOZ over MMR.
