I worship Code Geass, still adore Sailor Moon (not Crystal) have hate/love relationship with Naruto, always remember Death Note, among others.

I'm currently following good old Yu-Gi-Oh! and Gintama.

Both slow and hasty series have good and bad points. Fillers give some time to concentrate on the characters and learn about their traits while in some series you are completely dropped off if you skip any episode.
