It depends on the nuance.
People can choose to say 'looker', 'fit', 'good look', 'nice complexion' to mean handsome because they want to downplay it so they don't seem too vulnerable to admit that someone is handsome.
In this case though, good look sounds more general and not as fabulous as handsome, so it is like giving someone a 7 instead of a 9 in terms of looks.
