I havent see the animation Earth's Mighties Heroes one, so in TV/Film medium, I only see Thor in Chris Hemsworth portrayal
Regardless, the very best Thor portrayal for me is the Thor from writer J.Michael Strackzynsky (sorry if i have spell the name wrong) in early of Thor's return to Marvel universe. I don't know, but to me, that version is just so good, it stuck to me even after years I read the book.
The second best is during Jason Aaron's Godbutcher arc where Thor when he meets 2 different Thor (one from his younger self, and one from his future old self), I like it because here, in his most grounded self in his age, Thor can see the reckless,foolish, emotional, and aggresive self in his younger self at the same time he can see his future senile, tired, and broken down of his old future self. At the end, he is the only Thor who can have selfless act, and sacrifies himself to defeat Gorr.
SO far, along with MCU one, thats my 3 favorite Portrayal of Thor.
