Teed off shouldn't even come into this "vs" match. Doesn't hold a candle to the other two pins.
Congo is amazing imo. It's my favorite pin and I've played quite a few. Great shots. Both long (Volcano shot) and short (MAP saucer/mystery cup). Cool video modes.. yes more than one. Runs so smooth imo with the combo shots etc. Great colors with LEDS. Any the "Amy" voice is only on for about a second, so really, it's not worth mentioning. Awesome multiball start with the explosion of the volcano.
BSD sets the stage really well. Gets your heart going a bit. Not as much to shoot for and not as much going on as Congo. Mist is really cool, but then again so is the Volcano on congo... and Grey gorilla playfield. Fun pin with really cool sound and theme. Again, great with LEDS.
Really surprised with Dayhuff's assessment of Congo. Sold it THAT fast? WOW.
Congo wins it for me. However, I have both in the lineup and either/or are amazing pins to own. Just don't get that Teed Off over one of these others.
