The Zen games for the consoles are getting better with each release but the one I've heard that has the best physics on the consoles is Williams Pinball Hall of Fame.
The best physics on any system are on the emulators for the PC. Google "vpinmame forum" and that community should come up.
My main complaint with the Zen games is you can trap just about anything and a lot of the flipper skills don't work like you expect (bounce passes, post passes, etc). Casuals won't notice it, however, and will appreciate the eye candy in Zen games.
