Funny, because I've never had a single issue. About once a year I use a 3rd party application as a secondary scan, and you know what it finds? Absolutely nothing.
Fun or not fun, I have worked for nearly 22 years now with IT Security and I only talked by own experience.
One more fact Defender didn't even try to stop the latest versions of Wanacrypt and it's clones. Microsoft should stay away from AV products and let dedicated companies do that work.
But as I said that's only my experience during 20 years in IT business. If you trust Defender and feel secure than you should continue use Defender.
