I love Addams, but really love me some TZ.
TZ wins out for variety and overall rules. It's probably too complicated for the novice player to immediately enjoy, but not so complicated that it's not fun. Overall great code and rules, always something interesting to shoot for. Well balanced rules too, nothing is overpowering. A good mode player can catch up to a multiball only strategy. Interesting multiballs, especially power ball mania trying to score jackpots on the mini playfield. And some fun strategy in this multiball and modes being scored in bonus, as you can skillfully time when you hit the collect bonus camera award - how many modern games have a collect bonus?? No matter how many times I play the powerfield it's still fun and rewarding to spot the door and double the power bonus. The orbit magnets are super cool how they change the way shots go and set up key shots. The playfield layout in general is just different than any typical layout, which is always refreshing. The sounds in the game are top notch, just like Addams. Can't say enough good things about it. Pat says it's where he made things "too complicated" but for the pinball enthusiast there's so much to love about it.
That said, Addams will always be good, for many of the same reasons as TZ.
