Brawl was a gamechanger. Now that's not taking anything away from Melee. The moment-to-moment physics are better in Melee and Melee was a big step-up from the original. With Brawl, we got so many firsts for Smash..
-3rd-party characters
-A story mode with a lot of cutscenes
-Custom stages
-A massive library of music (for the time)
-Assist trophies
-Final Smash
-Online. Ok, well the online sucked. And the online has pretty much sucked since. But it is an option.
Brawl was in many ways, the first modern Smash. Now I'd rather go back to Melee because of the moment-to-moment gameplay and larger differences to Ultimate compared to Brawl.
But for me, every Smash after the original is amazing (unless you count 3DS on its own, but that's still an excellent release).
Tripping is just about the only complaint I have about Brawl.
