As much as the site "aims" to be impartial, it's hard to fathom how someone who "collects" viruses "for testing purposes" can be objective. For one, the tool used for identifying the sample testbed, VS2000 by VirusBuster (yes, I'm familiar with who he is), is built around the identification of viruses by, you guessed it, F-Secure and Kaspersky AV. Also, the products being used are home (or retail) versions which generally are more flash than substance. If you really need to test out a product's scanning/cleaning capability, use the DOS/CommandLine scanners of each, without the frills of fancy graphics.
BTW, it did not include a test for detecting and cleaning "In-The-Wild" viruses, something which should be mandatory for any credible AV program.
Just my 2cents,
