As a Melee player (I've never hidden this fact) I don't like the fact that Brawl dumbed down the game. All of the advanced techs aren't some arbitrary skill barrier, they're to be used as either mind games, to put yourself into a a good position, or to set up your combo. My issue with Brawl is that some of these great combos (going from 64 to Melee) were made useless and instead were made trading hits.
You want a fighting game? You have combos characters can make:
MVC2 Clockwork Combo
Tekken (don't really watch it so sorry if I picked a bad match)
Street Fighter
Super Smash Brothers Melee
Super Smash Brothers Brawl
Here's what I see in the Brawl matchup: I see players both being able to do actions after being hit, making it possible to get out of a move that should end their stock (game). I don't consider that to be up to fighting game standard. I don't think that Brawl having a wildly out of balance list to be competitive (and don't mention Falco and Fox because there's Sheik, Jiggs, Falcon, Marth, and ICs) and I don't find its randomly elements to be found competitive by any means.
When I say Melee is the best game in the Smash series I mean it. It's the most non-RNG reliant (hello Pikmen and tripping), it, arguably (unless you're Isai) more balanced than Smash 64 (which has actual 0-death combos).
Brawl has a slow game that has a few advanced techs and if you'd like
here's a list of other fighting games with advanced techs (ignore the Brawl link because it basically is a list of telling you that it's possible to swim and break the Reflector). Also note that I said few and not none, while the few that exist aren't actually that previlant to winning (unlike the techs Clockwork uses with his Strider combo in my link above with MvC2 or the techs that are used in SSBM or SF).
EDIT:
Brawl is sup-par in every aspect of being called a "fighting game" and while it's not as good as Melee it does have some benefits (the top tier is more spread out,) it shouldn't even be mentioned in the breath of the previous two games as it is no where near as skill dependent.
