Interesting discussion, Top on my list as per below;

Kaspersky
ESET

Kaspersky
Pros: because very good detection and very fast response added detection to new zeroday malware.
Cons: Sometimes heavy on certain system, i didnt know why, but as im computer technician, im bound to interact with many different types and models of pc and laptop. And i fount that this it the truth.

ESET: Pros, very light on any system, decent detection. Never interrupt any activities on PC, so pretty much install, it detect most virus, and work lighter that Microsoft defender it self.
Cons: The new malware and zero day detection are not that good (last i use this is on Dec 2019, so didnt sure if it has improve). Configuration and security can be extra hardened, but need extensive level of knowledge to edit such settings.
