Well, I agree when compare "Performance" and "False-Positive", ESET is one of the Top-3 in the list, ESET is a light-weight without many False-Positives (Low FPs in price of low detection rate too).
As you have seen in my signature, I use Avira Premium Security Suite in my Host machine because of it's detection rate (which has been best, always!) and light performance impact, comparable to ESET and even sometimes better since it has better quality.
I've found many bugs and lack of detection in ESET, also, to choose an Antivirus to install on a computer, a pirated version of ESET is not a good choice, when ESET can be cracked to use and it cannot protected itself from being cracked, how you can trust it to protected your computer?
For a free Antivirus, I highly recommend you to use avast free + Malwarebytes Antimalware to have best protection to even beat ESET in protection and performance ;-)
About that you named G-DATA, it's a protection made for enterprise systems and network with too many FPs and running 2 AV engine in same time (avast + BitDefender) made for Administrators to watch every suspicion file. (Like TrustPort which use up to 3-5 Engine on your demand).
But, you action and behavior in the forum has not been Professionally, if your antivirus failed to block a treat, you should not come and scream for your hate, but come and let us know about its fail and we will practice to prevent future problems and also help you solve the current problem. when you do this, you will help yourself and also 130.000.000 users else around the world!
