While I generally agree with most of what Alpha is saying, there's still the snobbish and absolutely silly notion that Brawl is more competitively inclined simply because it's less technical. Brawl is only one competitive outlet of many legitimate and near infinite possibilities in this world -- it's progenitor included, and as such, its level of entry for every competitive hopeful is only different when weighed against the varied possibilities -- not qualifiably better. In no shape or form.
When talking dexterity, specifically, to demerit the mindgame aspects of Melee because of the elaborate nature of its technical metagame is absurd, as you're doing two things:
1. Insulting the talents of those who cherish the culturing of their dexterity, which in many competitive outlets -- such as sports --is a magnetic trait for any competitive player to possess.
2. Blinding yourself with the absolute judgement that players don't have to apply mental faculties to make their technical abilities work. And that's stupid.
Yes, in Brawl, mindgames are more prevalent as a result of the various mechanics excised during the transition. But, I don't even think I need to go into detail here: Do you truly believe that Melee was an overall "stupider" game due to this variance? Are you really that unintelligent? I don't think so.
A more technically inclined fighting game rewards players with higher levels of dedication. That is all.
That skinny white guy you see on the sidelines at your neighborhood basketball blacktop stays on the sidelines, alone, because his lack of dedication to the sport shows. He doesn't hit the gym. He doesn't work on his jumper often, comes to play in blue jeans and a wife-beater, can't handle the ball with his left and his vert is about 10 inches. Unfortunately for him, and all others like him, the rim regulations won't change to accommodate him, neither will various markers such as the 3-point arc and free-throw lines, nor will the court size shrink to assuage his laggardness.
Eventually, he'll turn his back to that avenue and just go play Brawl, as basketball's requirement of entry is simply too unjust. While those Neanderthals continue to excessively work on their bodies, hone the forms in their jump-shot and dribble techniques, and perfect conventional high-level offensive and defensive playstyles through rote memorization; "skinny-white-guy" can go home, turn on the Wii and train his mind.
GTFO.
Stop trying to paint Melee enthusiasts as Brain-in-the-Jar automatons with robotic hinges in their knuckles. That portrait is anything but a manifestation of Melee's high-level gameplay. Melee offers diversity of styles and reward for dedication, much more so than Brawl (at this point). Just because a player has honed his technical abilities to an impressive level and manages to beat Azen or Ken despite not being as smart as them, does not highlight any sort of detriment to Melee's high-level play. It simply exhibits diversity in legitimate playstyles. Something welcome in any competitive oultlet.
And yes, being "technical" in Melee is a style choice.
Done.
