Disvow links vs 410 which would be better to remove spam links from google's index

So, a site of my was recently hacked and now has 50,000 indexed url.Almost all the links are un-natural links and I would like to get rid of them. They are currently redirecting to 404 page

Now I want to remove all the un-natural site and keep only my 500 natural links. So I've read many articles saying 410 redirect or disvow links from google.

Could you guys let me know which one works best?

Also do I have to re-crawl after the 410 redirect or after I have submitted the links for disvow?.

Additional info: The website runs on WordPress
