For home use, Windows Defender is fine, and you really don't need a third-party AV. For businesses it's Defender ATP, which looks about the same as every other AV/EDR product. Haven't personally used it so no comment, other than their Linux support doesn't look great right now. What slows down endpoints is usually shitty security engineering, and multiple pieces of security software doing essentially the same thing (my company uses three different monitoring tools which all hash executables). 9 times out of 10 you can blame some manager in your security team who bought unnecessary endpoint security software to cover their ass after they listened to a bullshit sales pitch.
