Mark Hamill as Luke. I’m split between whether his best performance was in Return of the Jedi, or Last Jedi.
I also liked Qui Gon played by Liam Neeson, i think he brought a humanity to Phantom Menace. I like Ewan Obi Wan as well in all 3 prequels.
I like Daisy as Rey. She had that same kind of youthful effervescent giddiness that Mark had in A New Hope, or as i call it Star Wars. I like that Rey, despite her humble origins she chooses to be good, and has a good heart.
