What's a good wake up attack in your opinion?
That's relative, but I do know what isn't an especially good wake-up: A wake-up that isn't invincible, can be stuffed rather easily, and can be jumped. Not to mention, it's super unsafe (which wouldn't be that big of a deal if it were fully invincible). If you get the timing down, you're essentially full combo punishing Aquaman for attempting to wake-up. I'm not saying scoop on wake-up is completely useless. It has two hits so it breaks armor, and it has hella reach so if your opponent isn't on top of you after the knockdown you might catch him off guard before he's close enough to stuff it. But I wouldn't say it's a great wake-up move. When I'm against Aquaman, I never really feel that I need to respect his wake-ups. I'm a Batman main too, and obviously that match-up is damn tough, but one thing I don't have to especially worry about is Aquaman's wake-ups.
