I'm a huge fan of both Meta Knight and Falco. I like to hit fast, and they both do just that. They also have fairly good recoveries, and especially Meta Knight's Final Smash is awesome.

Sonic. Plain and simple. Hit hard, fast, and then finish with a punch.

I usually play samus, but will sometimes go with link zelda (shiek) or pit.

Meta Knight and Falco fit me best. The underlying thought behind their application in my case is to open a can of ruthless aggression and spray. Rinse and repeat. Essentially, the way I play each is by chaining attacks to create an offense that racks up damage while creating space via relentless pursuit and continued assault.

tl;dr I like spam.

I'm a big fan of Yoshi, myself. He hits reasonably hard but is still relatively maneuverable. Probably not the best tier-wise, but I'm used to him.

Kirby and Toon Link are my mains, although I will often play Mr. Game & Watch, Luigi, and Lucario.
