Dream and Dreamboat both suggest that you admire him in a somewhat romantic way.. so probably not those too. :) On the other hand, you could use them with modifiers attached to clarify what you mean. Maybe something like, "Wow, I adore Trevor Noah. He's kind of my idol in a way. I think he's incredibly talented and he's got great comic delivery. I really admire the range of issues he covers on his show and I respect his personality - at least, from the way it comes across to me! I guess you could say he is a bit of a dreamboat but I don't really think he would be my type, romantically speaking!" ;)
