I don't even remember anything from Spectacular, that's a bad sign when I don't remember. I think I remember it being decent/good but not as good as TAS. Wasn't there some love triangle, and Peter getting blue balled a lot.
Spectacular was only 2 season also, not a lot of depth. TAS was insane with the amount of stories and character building in it. It was overflowingly frantic at times, with the Sinister Six running around, Venom, Kingpin, Punisher, Kraven, Blade & Mobius to name some, and even small characters had episodes like Robbie with Tombstone, JJ's kid astronaut, etc. It was all jammed packed to the max!
No way, TAS was the best by far. I only watched the series once when it aired, and I still remember. Unless it didn't age well, or my memory's faulty, nothing has beat it since. That's not to say other stuff isn't good.
Just admit it, tiger, they hit the jackpot.
