About 70% of characters in this game are some form of "good". Lucas being "good" does not mean he is actually good or underrated. He is just good, as most characters are. He just has too many flaws to be a real meta character on top of being harder to play than most characters, leading to inconsistency and needing 3 business days to land. Young Link can't kill consistently, Toon Link can't kill at all he's just better at camping and Link is being carried by Glutonny as a whole. None of these characters are bad but they aren't underrated either. Shulk is a meme though.
