My friend hasn't unlocked all of the players yet, so I played the SSBB at church, which has all the unlocked characters.
Anyways, I figured that I'm pretty good with Pikachu (still), but because he's overused at church so much, I changed to Lucario. Even though I'm not that good with him yet, I can still use him pretty well. He's a bit hard to control, though, in my oppinion.
Then, when I played as Falco or Fox, I commited suicide, like, three times, thanks to the side b move. I don't think I'm that good with them.
On to some other characters. Well, I played as Pit a few days ago at my friend's house. Why? For one thing, my friend uses Pit in every single brawl, and she's really cheap with him. Second, I just wanted to use a character that I've never used yet. So I used Pit, and at first I tried to be cheap like her. I found out that that wasn't the best fighting style to me, so I reverted back to actually planning my moves a bit. Beat my friend in about a minute or so.
Then, there's the last person that I've used. Sonic. Even though he's good, his fighting style just isn't... me. So I don't really like him much.
So, all in all, after trying out more characters, I have decided that my best character is still Pikachu (probably from years of using him from the original SSB to SSBM to SSBB), and my second best is Lucario.
