The Shadow. You can spam the orbit for shadow loops, or you can spam the ramps for vengeance (if you're good at comboing, you can go for super vengeance), or spam the battlefield. Alternatively, you can ramp up the bonus multiplier, and stack up modes with vengeance for high scores. All around a great game with tons of different angles.
BSD is like this too.
Honorable mention goes to WH2O. You can either make your way down the river, or try to stack up your 5x with multiball or bigfoot hotfoot or mega millions. My buddy got a high score just going for the insanity falls record.
