X-Men and Spider-Man are pretty much the best examples of how you can take classic comic book story lines, adapt them for a Saturday morning cartoon show, and not totally dumb it all down. It was essentially my introduction to the full history of these characters and worthy of my eternal love based on that alone. That said, the DC animated universe is how the best example of a well written coherent cartoon universe out there. I believe it's made up of shows for adults as much as children so I have to say I like it more (especially being an adult now and all). I just wish they'd release the X-Men and Spider-Man animated series on DVD already. How am I supposed to lose myself in childhood memories if they won't give me these shows in DVD form?
