I agree, i do like the explanations. Just for consistency sake, here are my top 10 plus HM's, and the reasons why.

10. The Batman
A very cool version of Batman, it's on this list because of the great stories from the third, fourth, and fifth seasons. Although it started off rather slow, it's a great show for several reasons. First, I loved what they did with the Joker. They took a character who was firmly established in the DCAU for being neat and making sure he always looked nice, and replaced that image with a clown who didn't wear shoes and had wild hair. AND. . . IT. . . WORKED! at least for me, I love that Joker, and I always found him very funny. Also, Clayface was brilliant, I loved all his episodes. Their other really amazing villain had to be Clock King. Although he was a little different than his comic book counterpart, the episode Seconds is one of the best episodes of any cartoon I have ever seen. Finally, a great take on Batgirl and Robin, both were very funny. If the first and second season hadn't sucked so bad, it would have been much higher
9. Robot Chicken
Now this is a show that I love because of it's random funnyness. The first episode I saw was their Star Wars parody, and I was HOOKED. Really a very good comedy, mainly cause it doesn't try to be anything resembling a show plotwise, it's basically clips of this and that here and there parodying random things that are all really funny. I hardly ever laugh so hard as when I am watching Robot Chicken.
8. Recess
Although most of the slew of kids shows that have popped up in recent years are poorly made or completely stupid, I always enjoyed watching Recess. The teacher was hilarious, the kids were very funny, and the random plots could make me laugh. I haven't watched any episodes since I was in Junior High, but I put it here for being easily the best kids show of the decade in my opinion.
7. Wolverine and the X-Men
This is one of the best shows currently airing, as it attempts to use time-travel in order to make several entangling plots, and it does it quite well. The episodes in the future are very good, with the best of the future characters being Bishop. The biggest problem is that too many episodes were Wolverine focused, but overall the new take on the characters is very interesting and produces several great episodes.
6. Kim Possible
Ok, I must admit for as stupid as it looked and sounded at first, I very quickly became a fan. This is stupid action comedy at its best and i can't help but love it. My favorite villains are Senor Senior Senior and Senor Senior Junior. They are hilarious. Of course, the main villain, Dr. Drakken is also very funny, and his sidekick Shego is great(and usually the brains of the operation). Another plus is that one of my favorite actors, Will Friedle, is the voice of Ron Stoppable, the funniest character. Finally, how can you not love a show that features a Naked Mole Rat as a main character?
5. Batman Beyond
And here is another show with Friedle, this time voicing the new Batman, Terry McGuinnes. There were several great things about this show, including the fact that it was willing to explore deep and dark themes and wasn't afraid to show death(and it frequently did). The portrayal of Bruce as an old man is really very revealing into his character, and his effect on the people around him. The first season was quite epic, finishing off with a battle with Blight, who was easily the best Batman Beyond villain created. Probably my favorite episode though, was the episode Meltdown, which was both tragic and epic as it revisits Mr. Freeze in his best appearance ever.
4. Family Guy
Although this had taken a turn for the worse the last two seasons, this season has been awesome and reestablished it's place here as one of the best cartoons of this decade. This really is a very funny show that sometimes pretends to have a plot but is really just running gags. Favorite character is Stewie, who although better as a baby with plans of world domination(which was revisited in the Stewie kills Lois/Lois kills Stewie 2-parter) is still very funny. Great show overall and very rarely ceases to make me laugh.
3. Justice League
Another epic show from Bruce Timm and the DCAU, it featured 7 of DC's best heroes collaborating together to fight injustice and protect the people of earth from danger. The first two seasons were epic, with The Savage Time, Secret Origins, and Injustice for All some of my favorite episodes. Best character is a three-way tie between Batman(who is just as awesome in this as in B:TAS and Batman Beyond), Martian Manhunter, and the ever hilarious Flash. Really such a wonderful show, it lost a little bit of it's charm as it went to JL: Unlimited, but it's still an absolutely amazing show.
2. X-Men: Evolution
My personal favorite take on the superheroes known as the X-Men. Did it suffer from a slow start in the first season? Yes, a little, but I look on that as a necessary evil because it took the time to get us invested into each and every character so that when the epic plot of the Apocalypse storyline took place, it would have a more total impact on the viewer for what happened to each and every character. Both the third and fourth seasons were epic, and after the glimpse into the future, I was always very sad that it never continued on into a fifth season.
1. The Spectacular Spider-Man
For probably the biggest DUH on this list, TSSM is my favorite show of the decade. Why? well, of course it IS a cartoon about the best superhero ever, Spider-Man. But, more importantly, because it is a cartoon that works on every angle in almost every way. There is humor, in fact, there's a LOT of humor, and it's actually funny. There's drama, most noticeable in episodes like Shear Strength and Intervention. There's complicated yet very precise plotting that always has you guessing, the best being the Who's the Green Goblin? plot. overall, this show is nothing short of amazing, and I hope and pray that it will be back for a third season.
