Half of comparisons (3 of 6) are not performed on the same frame. That alone is enough for me to not even consider reading what author has to say. No mater how short actual comparison is.
I'm not saying that one codec is better than the other. I'm saying that author of this "review" has some way to go before we can take any of his comments seriously. Besides, if "free" was reason for comparing them, why he didn't use free encoders instead of commercial ones? Again, FAIL!
