Matt Damon should've won Best Actor for Good Will Hunting

I've felt for a long time that Matt Damon should've won the Academy Award for Best Actor for Good Will Hunting. Now we know he won Best Original Screenplay with Ben Affleck, which was rightfully deserved, but I feel he should've won over the other Nominees. They were all good, but I feel Damon was stronger, especially since the performance he was nominated for an Oscar for was essentially his breakout role.
 I'll give you some descriptions of all the nominees that were nominated in 1998:

Matt Damon in Good Will Hunting: Damon plays Will Hunting who is a math genius, but even though his friends, particularly Ben Affleck, want him to succeed, Will doesn't want that type of life. Even though he works with a math genius, played by Stellan Skarsgard, who wants him to use his potential as well, though he may be just using him for personal gain, and Will sees a psychiatrist, played by Robin Williams, who want him to do what is right for himself and to let people in, but Will is skeptical about the whole thing, especially when learning he's an orphan which does , hope I didn't spoil anything for anyone reading. Even his girlfriend, played by Minnie Driver, seems to want him to use his potential and let people in.

Robert Duvall in The Apostle: Duvall plays a charismatic preacher who constantly sleeps around. And his wife gets upset, starts sleeping with someone else, and gets the church to — whatever it is when they’re no longer an official preacher. No defrocked, because he wasn’t that kind of priest. He touches farmers’ daughters, not little boys.

Peter Fonda in Ulee’s Gold: The film is about a beekeeper who is raising grandkids because his son is in jail and his daughter-in-law is a drug addict who has disappeared. And his son begs him to find the daughter-in-law and bring her back. So he does this, and they bring her back, try to help her detox, and then him dealing with his son’s criminal associates who want some sort of hidden money their son has.

Dustin Hoffman in Wag the Dog:  The film is about a Bill Clinton-esque President (the film was released before the Lewinsky thing) who, two weeks before reelection day, he was alone in the oval office with a dancer, who claims the president harassed her


Jack Nicholson in  As Good As It Gets: Nicholson, misanthropic author who becomes a better person with the help of Helen Hunt and his gay painter neighbor Greg Kinnear. The film is good, and so is Nicholson, who won the Oscar for this film. The only problem is that Nicholson has been playing this type of character for a long time. You may say that he started playing it in One Flew Over the Cuckoo's Nest and as well in Terms of Endearment, which he also won Oscars for, but now in the 90s we've seen it already and there are other movies he acted this way, Batman for instance.

My point is Damon played a character that could've been a part that any other actor that came to play him, might not have worked at all. Damon, yes he did write the part for himself, but I feel you'd want to do justice to the character you wrote on page for yourself to translate to film as well. That wouldn't be an easy feat to do, and the whole film is amazing as well as the performance. Now, these roles are all different, but still, in my opinion, Damon stands out the most. His character has depth that we see come to light throughout the film, and I still feel there's a lot we don't know about Will Hunting. The other nominee's characters do have depth, but, to me at least, not to the level as Damon's portrayal as Will Hunting. That's just me, but I could be the minority on this...
