Let me clarify my position on tests. Even if an absolutely scientifically rigorous test was to prove without a shred of doubt that product X is the absolute best, most complete protection available against all kinds of threats and I was using product Y, I wouldn't just drop product Y because:
1) I already paid for the license
2) It's already installed, configured and running on my computers
3) The protection afforded by the best is probably less than 1% better than whatever I'm already using.
The only reason I'd switch immediately is:
1) a critical vulnerability was discovered on whatever I'm using, it's already being exploited and the vendor refuses to acknowledge or fix it.
2) some update/patch crashes or blocks something I need and there is no way to know when it will be fixed and no way to bypass it (actually had it happen with Bitdefender once)
3) my license is about to expire and I find a killing offer for some other product.
In other words, I have no favorites, I have used mostly anything that offers a good price in my country and always recommend to test any product before buying whenever possible.
