I hate her Uair so much! I just fought a really good Samus who would bait you near the ledge and Uair juggle you from the ledge. Her Uair is so good and so freaking annoying! Also, I felt the power of OOS Screw Attack...
Combined with Fair, Uair, Zair, and hell, a read with Charge Shot, Samus has options if she's at the ledge.
Fox's little range makes me feel sad when his Ftilt does nothing while Samus's slaps a metal boot to his face... Speaking of which, Fox's Dair. How much of it affects his game, especially landing and preventing people from challenging him in the air. Nair's a sex kick, so it makes sense, but Dair staying out for that long makes Fox feel a bit safe if he's in the air and someone screws up a follow up.
