Growing up I would say Tom Hanks, but I haven't really cared to see any of his movies from the last 10-15 years so for me personally I can't still say the same, I'm sure he's still just as good though.
Always been a fan of Denzel Washington and a lot of his messages in several of his movies. Sadly they get lost and forgotten as his opinion is definitely the minority compared to the rest of hollyweird.
I can't really think of any other top of the top actors, but there's several I enjoy watching I would consider great.
