Can't go wrong with either. Never owned TAF, but have played the snot out of it and would definitely own it if I ever found one for the right price (read: wouldn't pay more than $3750 for one, so I guess I'll never own one, lol).

But if I did own both, and had to choose which to keep I would definitely stick with TZ. For some reason that game for me has a lot more satisfying shots, strategy, and it just a lot more fun to play. And there is just something very pleasing about the way the lights strobe and the sound that goes along with the rocket shot across the playfield after a skill shot

What kind of prices are we talking here, honestly if you can swing it, there is such a demand for both you could easily scrape some funds to get both of them; play them both, decide which you like best, sell the other one (probably for a slight profit if you get a deal on them).
