I've have both, the 590a1 with the ghost sites. And the 500 persuader with pistol grip and heat shield.
I personally like the persuader more only because its lighter to carry around.
The 590a1 is a VERY solid shotgun compared to my 500. The entire piece is made of a different and thicker metal. Like someone else said, the 590a1 is a tank! You could also use it as a baton or baseball bat and it would never dent.
