Professionals say it is Meta Knight, but remember it is an opinion!

Ike,Link,ness,and lucas
It really depends on the user of the character. any character can be the best but also the worst
i Think is dk
There is no best because the person has to fit the character.
There is no single "best character". Try them all to see which one is best for you!
According to SmashWiki, Meta Knight is supposed to be the best.
Master hand is not a playable character in brawl.
It all depends on personal opinion.
I think R.O.B. is pretty good.

The way Smash bros. is designed,there isn't a best character, every character has they're own strengths and weaknesses. Smash Bros. isn't an ordinary fighting game!(Technically its an action game)You have to find the fighter that best suites your style. I'm good with all the characters, but my best is Ness.
