there is no end debate on this, since each user have their own preference. in my opinion, windows defender should be the most basic defense line needed to protect your device. And remember don't simply open any links and visited some suspicious or shady site. Because defender may ineffective against some high risk threat like ransomware and zero day attack.

the most important is keep your os and program updated from time to time, so any exploit or vulnerabilities get patch up.

if u still insisted on getting 3rd party av, please proceeds to some review site to checkout the product available in the current market.
