TJ.

TJ saved Tommy's and Kat's life without powers. He fought for the helpless and was completely selfless.
He was picked by Tommy to become the next Red Ranger.
He was always level headed, and managed to lead while also putting up with Demitria and Alpha 6 (I commend him for that).
When put in a pinch, he always weathered through, making the sacrifices necessary.
When given a new set of powers, he gladly stepped down from Red to Blue, without complaining in the slightest.
When he was forced to fight a superior counter part, rather than making a one off gadget, he instead used creativity and ingenuity to defeat them (Employing both the All blue thing to throw the Psychos off as well as coming up with the Psycho Silver trick).
He continually went on quests to find Zordon, examining other planets, proving he never gave up hope.
He was willing to sacrifice himself to save the civilians during the invasion of Earth.

He saved the entire galaxy. He has a flying car. He was almost baked into a giant pizza.
TJ is the man for the job, in terms of power, in terms of personality, in terms of ability.
