Making a graphic novel. Do I add text in Ps or Id?

I'm in the process of making a graphic novel. I have the illistration part down but have yet to mess with text. My thought is to place a Ps image into Id then do the text in Id. It seems like this would be easier if I have to edit the text down the road. Is there any reason not to do it this way? Can Ps do things with text that Id cant? Thanks.
