What mythological pig was the greatest?

I was looking up the Erymanthian Boar and discovered that there were, at least, two other Greek pig monsters, the Calydonian Boar and the Crommyonian Sow. All three ravaged the land they roamed. Yet the Calydonian Boar and Crommyonian Sow were both killed (one by a massive hunt consisting of several heros, and the other by Theseus), and the Erymanthian Boar was captured (by Heracles). I can find no real comparison between the three (aside from the fact they could be grandmother, son, and grandson to each other, but that's only in a few things I read), and I can come with arguments, based on what I've read, for each to be greater than the other two, or even all about the same. I was just wondering if there was any more definitive comparisons between the three.
