In your testing were the products at default settings as everyone tests? I'm betting that if you threw EIS Firewall and HIPS into "interactive Mode" then in advanced settings enable choices such as run time packers and advanced heuristics/DNA signatures in objects to scan, and scan options, set cleaning level to strict cleaning, which attempts to clean/remove without any user intervention with in all of the Threatsense Parameters, then enter firewall settings to advanced/IDS and Advanced options for a little more control, and then test Eset, you may just change your mind...
Eset is powerful enough to run on its own and keep up with any big names out there. With choosing between the 2 products listed here, the only choice needing to be made, is does the one or the other fit the users needs and uses. Both are quite capable of protecting systems.
