Favorite/Least favorite saga?

The title says it all, what is your favorite and least favorite saga in the Pokemon anime and why?

My fave saga would have to be Sinnoh, especially cos I loved Dawn. She was my fave lead girl in the anime and the battles were epic.

Least fave for me would have to be Orange Islands, I hated Tracey.

Favorite so far is either Johto or Sinnoh. Johtofor nostalgia reasons and it's was really good. Loved the old crew and the theme songs where the best and I really liked the cods and re-occurring characters like Casey. Sinnoh I haven't seen all of yet, but it's starting to grow on me. There's a lot of well written episodes and Dawn is one of my favorite females in the series.

Least favorite was the Orange Islands saga. It wasn't really memorable and only lasted one season. The song didn't stand out to me much and I don't like Tracey who wasn't memorable either.
