Who is the strongest follower in Skyrim?

Lydia is the best Skyrim follower. I am aware, I know. The Huntress is Aela. Aela was a competent warrior before the Dragonborn arrived. The island of Barbas is named after it. The Lioness was named Mjoll. J'zargo is one of the five. Annekke Crag-Jumper is a woman. The Serana DLC is called Dawnguard. Dragonborn DLC is named after Teldryn Sero.
