the madman has a very long pause, and I'm afraid it's mostly ukegrating anyways... not the worst I've seen though, by far
the second madman is better, as you said. Not for the reason you stated, though. In my opinion it's better because of the cleaner strikes in it.
Nothing bad about grabby decaps, but that's only if you follow up with a combo. A decap as the only feature of the replay isn't enough to justify a grab, in my opinion.
