DSmash and USmash are slow but strong (USmash is the slowest USmash). FSmash is fast but weaker, especially with damage, and its reflection bonus seems Minot (definitely not x2 like Ness's). Dash attack has a sweetspot that can kill. Jab is good. Tilts seem good, I've heard DTilt can be interrupted but air don't know specifics.
His throw game is solid. DThrow leads into a lot of stuff (DI dependent) and all his other throws can be killers (UThrow is stronger than ROB's). Of course, this is a little balanced by his difficulty landing grabs with his being a bit laggy and not having Ness's PK Fire to help land them. But ZAir seems to set them up at lower percents.
