I went with CCW Safe. When I was making the decision (2 years ago), it committed to unlimited defense funds and was much lower cost, especially if you have your carry permit.
They have a good podcast (on iTunes) too.
Things may have changed in 2 years, there are tables comparing the products you can look up.
Not sure about the others, but CCW Safe is officially "prepaid legal". Offering a "Insurance" product makes you susceptible to volumes of insurance regulations and regulatory agencies. It was one of the first tools NY used to hammer on the NRA.
