I can only say these 2 things:
1- I tried Kaspersky AV for my MBP back in 2015, and I noticed that this App was sending constantly some kind of data to its server since I saw my internet connection always at full capacity even when I was not sending nor downloading anything. So I decided to delete the App. I did not like the idea that an AV software was constantly sending something from my hard drive to a server.
2- For my PC and Mac, recently, I purchased it again to use it to block the ads and some tracking going on the background during web surfing (be it Safari, Firefox, Chrome, Edge). Since I noticed that on my Windows PC Kaspersky was blocking all of them, and I could see the actual sites and trackers trying to get what kind of activity. And more: Kaspersky alerted me that even some Apps that I did not suspect were attempting to access my webcam. So, when I installed it on my MBP, it also showed me the trackers that it blocks, and many more. It was quite astonishing to see that a 5 minute surfing on a social media, or watching a 5 minute video in YouTube, Kaspersky was blocking up to tens or even 100 trackers and ads. So on my Mac, I use Kaspersky mainly to block ads, and trackers. And on my PC, to protect against virus, and other things.
So, it is up to you.
And from my 20 year-use of Macs, I do not recall getting virus threats on my Macs. And lived most of those 20 years without AV on my Mac, excepto for now, but for the reason I mentioned above.
