I have STTNG.  When you get it going the flow, speed, and lights show are unbeatable.  It keeps me coming back after several years.

On the down side, STTNG has a big open playfield with heaps of space between shots.  So, if your shots are a bit off, you hit nothing and quickly drain the ball.  Depending on my mood, it can also be a bit too 'stop and go' for my liking.  That's when I prefer something a bit fast and flowing like Whitewater or Funhouse.
