I like how the knocker is incorporated into Seance mode on TAF.
Bank Bust on Spiderman is my favorite mode on that machine for some reason. I like the full-orbit launch of the second ball to hit the ball off the magnet. I've heard this mode is great with a shaker motor, which is on my wish list.
Graveyard is fun on MSF, collecting the body parts to make a monster.
And I really like Dance Party and Whack a Gofer/Chicken! on my NGG.
