Worst era of Warrior Cats?

Worst era of Warrior Cats?

Well, according to me, I would divide Warrior Cats into 3 eras.

First era

The Prophecies Begin, The New Prophecy and the Power Of Three

Second era

Omen Of the Stars, Dawn of the Clans and A Vision of Shadows

Third era

The Broken Code, A Starless Clan and Changing Skies

I'm still on the first era, so I wanted to know about the fans' opinion. My prediction would be that the best era would be era 1 tied with era 3, and the worst era 2.
(including super editions, novellas, mangas... to each saga)
