I own it and I think it's a cool machine. Love the theme, love the music. Can't go wrong with poker. Feels more sturdy than other DEs IMO (those pop bumpers seem way less lazy than on other machines I've seen, and machine has a general better feel I think).
I modified the settings to make it harder to lock balls so they don't go as often in the paddlewheel. I have to disagree with you about the modes though. It seems to me that they're all pretty much irrelevant besides the one that allows you to get free balls (forget the name, the one that makes you do the loops).
The scoring is unbalanced as making your poker hands pays a whole lot more than anything else (multiball included), unless you're good enough to hit that captive ball repeatedly.
Nonetheless, I still think this is a pretty cool game.
