Getaway all the way. Good Ritchie speed and flow, awesome and classic theme. T2 is a good alternate, but not as fun as Getaway.
Congo is just meh. Had one for 3 years, and while the music is great, it's just a bunch of disconnected modes that occur periodically as you accumulate MAP, ZINJ and GREY letters. The main toy looks neat until you realize you just have to beat on the flippers to complete it every time. Wizard mode that is basically the main multiball with the bottom PF enabled (more flailing). I did like the skillfire mode and the volcano barfing balls all over the place (leave the tab busted off the top for "ball is wild" fun) .. but wasn't worth keeping the whole game for.
