I've heard a few people say that the Sonar is a PN-2 killer , would like to A/B them. The Idiotbox Mad Dr is also a worthy contender!

I think the same. The PN-2 will always be great for hard chop, but the Sonar has so many added features (tap tempo, multiplier, machine, the Delta control...) that it makes it very versatile.
Copilot FX have another tremolo worth checking out, it´s the Polypus and it offers cool tweaking on tap. But I´m not sure if it´s good for hard chopping purposes.
