Fast Draw is my favorite EM (so far).
Why? Of course, the neat feature is, drop all 10 drop targets and the center horseshoe targets start resetting for 5000 points each, as long as you can keep hitting them. Aside from that, the playfield is fun to play on. There's 4 inlanes. Lots of nudging to keep the ball out of the outlanes because the rebound off the drops tends to go towards the opposite outlane.
You can play the upper playfield for safety and build bonus and points up there with good pop bumper action and kick outs worth up to 4K. Or you can test your skill with the drops.
"Speed Count" bonus rapidly counts down after each ball with max bonus on ball 3 of 45K.

I also have really enjoyed Fireball. Great skill shot, and because of locking balls, you can plunge quite a few balls in a game. Always fun to get multiball. My favorite shot is hitting the captive ball to the top. If 2 balls are locked, one is released into play and the other goes back to the shooter lane where you can plunge it right away for 3 ball multiball,or save it in reserve. The game gets wild. But at other times you can be careful and deliberate, when the zipper flippers are closed.

I love smacking down 13 drop targets with 2 inch flippers on a fast, open, playfield on Pop A Card.
Lots of nudges for outlane saves. It's very challenging to hit the lower stand-ups off the flipper when they're lit for WOW. It's also fun to hit them by nudging the ball off the sling shots.

Also enjoy Centigrade 37.

Many others I know are good but haven't got enough time on them yet.
