Detects a bit less AFAIK, but doesn't have insane misfeatures like "web protection" (MITM) and auto-installed plugins/whatever that you have to disable one by one, bloat related to 1st point, scare popups to get you to upgrade/renew/etc, and the general scummy BS that comes with having a 3rd party antivirus.

I think it's good enough, in general. While a 3rd party AV might be more effective for someone very prone to installing PUPs/malware, I still don't think it's worth it - an adblocker likely makes much more of a difference just by preventing people from clicking Google ads while looking for legitimate software.

Side note: I've been happy with Win10. While I thought auto updates would be bad, they've all been snuck in while I'm sleeping/AFK with no side effects. Apart from the initial round of disabling various telemetry features, it's been smooth, and the stupid stuff like unremovable start menu tiles has gradually been fixed.
