I decided to take a quick look at the speed difference between running u-smash, skid stop u-tilt, and short hop u-air, which are Mega Man's most damaging attacks that can be done quickly out of a dash. This is what I found.

U-Smash is the fastest, it comes out on frame 8.
U-Tilt is the second fastest, it comes out 10 frames later than U-Smash.
U-air is the slowest, 12 frames later than U-Smash.
Dash Grab comes out on frame 8, same as U-Smash. Mega Man's most damaging throw does 11 damage. Whether you should do this or U-smash depends on how close you are to the ledge behind you and whether they are at U-Smash's kill percent.
Nothing too mind-blowing but it is something to keep in mind when choosing how to punish your opponent.
