Jeffrey Hunter conveyed everything I needed to know about Captain Pike, and I can imagine the great adventures he had along with his crew of the Starship Enterprise. He's an interesting character and I would like to close the book on him. Greenwood was planted as the Obiwan Kenobi role for Chris Pine's JJ Kirk; the mentor to teach Kirk something... but I wish I knew what it was? Mount is only there on Disco just to make their character Burnham look better, the latter versions of Pike were positioned to support the lead actor and not make an impression they would have their own series. Objectives were different from "The Cage" to JJTrek and Disco.

I really don't get all the TOS Pike stuff. He was in a failed pilot, and then his footage was edited into another episode. That's it!
Greenwood was much better. He basically saved Kirk from a meaningless life. He also kicked Kirk in the ass when he needed it.
As for Mount (no spoilers for DSC here!), he is fantastic in DSC, IMHO, and is not playing second fiddle to anyone.
