It all depends on the user, what kind of protection they need, their learning curve and their installed software.
ESET-
Will protect against the most common malware.
Easy to use and configure.
Simple learning curve required.
Compatible with most other software.
Lite on the system resources.
Better for users who know how to browse the web safely and safely download files. Also better for users who don't like to learn how to learn new things.
Emsisoft-
Will provide better protection.
Somewhat aggressive- false positives are expected.
Will require some learning to configure and use.
Tweaking maybe required to make it compatible with all your installed software.
Also lite on system resources.
Offers better protection for users who don't know how to safely browse the web and safely download files. However might be a bit too difficult for some users to learn how to use effectively. Advanced and paranoid users love it.
I will vote for ESET because it will be better for most users as a whole.
Enjoy!!
