My worst experience with this show was the first part of the storyline where Spider-man teams up with the X-men. The day part 1 aired, FOX preempted the entire "FOX Kids" block with coverage of the Pope in NYC. When the show returned the next week, they skipped straight to the second part, leaving me utterly confused about what was going on.
I think X-men evolution was the only Marvel cartoon that came out before I went to high school that aged well. I could watch episodes of that show on Youtube right now and still enjoy it.
Spider-man TAS came out when I was 6 and ended when I was 10. The show ended with no payoff since he STILL never found MJ. Spectacular was a much better show overall, I just wish had an art style closer to X-men Evolution which was a much better looking show overall compared to every other Marvel cartoon since.
