You are free to make a choice. What is the reason then that you're using ESET? Generally it is recommended to test various AVs and use the one that works best you.
I must be looking at different results then as to me, the real-world results show ESET with no false positives. This puts it at the top of that category. The difference between ESET and the others in the protection category is 1% which in reality is nothing at all especially when we are talking about between 99% and 100%. It gets much worse though when you look at the number of false positives for the companies at the top of the protection list. Most of them are all at the bottom for really high false positives.
Security isn't just about blocking every single thing that a user may interact with. If a user is constantly being annoyed by false positives then they are going to start turning the anti-virus off occasionally so they can do what they want to do. The same with if they are trying to use their computer and they can't because they see the anti-virus hogging all of the resources. These things all need to be carefully balanced in order to be the most effective.
