How does Panda Cloud fit into the list of free AV´s?

If we may believe PCMAG reviewer Rubinstein, it tops Avast! and is their recommended free AV (they have no recent test on Avira Free though).

I still think Panda can be added to the list of Avira and Avast and AVG is the least recommendable of the four, it got kinda bloated, its link scanner has caused more than one problem and it ranks lower in detection rates than the others.
