Nice rundown
Aside from a few things I think it's really more choice, which application suits you. I think the best of both worlds is to use both, at least for finished work, line drawings done in Illustrator and rendering done in Photoshop.
Photoshop allows for infinite rendering possibilities, may of which aren't available in Illustrator. ***BUT, in Illustrator the lines and shapes will always be superior from a printing standpoint as you can enlarge and reduce the image and the lines stay constant. That right there is what Illustrator does best, allows for resizing without any loss in sharpness.
At least that's what I know based on my experience
