What is the best tool for cutting foamboard/rigid foam insulation?

Comparison test of various foamboard cutting tools. Thank you to all of the commenters who gave suggestions!! ... Sorry if I missed yours. Forgot to mention hot knife--but it won't work on this type of board due to the fiberglass paper doesn't melt. The foamboard is GAF EnergyGuard. The best tool!!
