Fireball Em would be a worth Grail for anyone I think

I don't really get why this machine gets so much love?  I've got the SS version and I think it's pretty similar main exception being lack of zipper flippers.

The art work is pretty good, the spinning table, seems to go off fairly randomly.  The main thing I like is that it's easy to get multiball and the machine has no respect for who captured the ball.  So your mate locks two balls and drains and you come along and grab them.  The SS also has really cool sound effects in an early 80's way.

But can someone explain why the EM is so revered?
