Most of the time, I use either ESET or Kaspersky. I appreciate Kaspersky because they’ve consistently been among the first to detect and publicly report so-called state-sponsored trojans—especially the ones that ended up getting them banned in the U.S., which I personally find quite admirable. 
Another reason I like Kaspersky is its strong offline detection capabilities—not just cloud-based protection.
ESET, on the other hand, is my go-to for being fast, lightweight, and still offering above-average protection.
On my main PC, I still use ESET, while on the living room and bedroom PCs—where I’m not the only user—I’ve switched to Kaspersky.
As for BitDefender, I’ve uninstalled it from all systems and canceled the subscription (or had it canceled), mainly because it interferes too much with certificates and often had a noticeable negative impact on performance.
