RE: The official Super Smash Bros Brawl thread.
I've found Wario and King Dedede to be very difficult to use well. Their attacks are very slow, and Wario doesn't really have any good specials that stand out to me, which is disappointing, because I hoped Wario would be a lot better. Snake is fun to use, but very difficult to use well. Against someone like Fox, he is done. Sonic has good speed (of course), but lacks good KO attacks. ROB has some slower, but strong attacks. I like his B and down-B specials. His laser is nice for matches that involve more than 2 players.
Lucas has been very outstanding for me so far; he runs around Ness in circles in this game. His version of PK Thunder is so much better than Ness', since it strikes multiple times, bends in sharp angles, and sends Lucas flying farther. I'll also use his PK Fire on occasion, but I'll rarely use his PK Freeze, though.
Pit has also been fairly reliable. He has a good balance of speed, offensive, and defensive abilities. Meta Knight also seems to be very good, as his attacks come out right away, but I can't find a good attack to KO the opponent with.
Right now, I am trying to get more CD's (Galactic Battle, Snowman, Super Mario Land Underworld), and figure out what the best stage-building strategies for the stage builder are. I cannot find a way to connect ladders to floors, which is kinda disappointing.
