Badger is 52 feet. I've seen it played really straight (Norm Duke won on it by laying the ball down on 15 and letting the ball hook 2 boards to 17, which is the pocket). And last year some guy won it (or nearly ran the ladder) by lofting the left gutter cap with a super strong ball and a super high rev shot that sort of fell back to the pocket).
"Harder" than Shark? Well, it depends on the player.
I won a no-tap tournament on Badger last year playing it really straight like I saw Norm Duke doing. If you know what to do on it, it's like anything else. If you can execute, you'll do okay. But if you keep throwing the ball away from the pocket, you're not going to have much success.
