I prefer the painterly process of photoshop, as I use photohop with a Wacom graphics tablet, you cant get quite the same expression with vectors. But you are right, I will always bounce between Illustrator and Photoshop for my professional work.
Trips and I will usually collaborate as well, he will do the vector art and I will smootha nd texture it in photoshop.
I will try post up examples of Trips' vector work and some before and after stuff.
