I don't see Avatar or Korra on your list. Both are phenomenal shows (although they might skirt too close to the "anime" line) edit: I just spotted Korra in the plan to watch list. Watch it. It's good.

If you're okay with 3DCG animation, my favorite cartoon of all time is Reboot and there is currently a project ongoing to restore the original renders into HD, with newly restored episodes being uploaded to YouTube periodically.

And if neither are your speed, another user here recommended Gargoyles, which is also a phenomenal TV show
