For what it is worth, I started with Campaign Cartographer, I found it cumbersome and a steep learning curve. I migrated to Photoshop and have never been happier. PS has a serious learning curve too, but it is much more powerful. Plus you get to try all the tutorials on this website. I am self taught in PS, and in some ways it was a long journey, but I know I am better off because of it. I make way better maps in PS than I ever did in CC. So, if you are starting out and considering which way to go...I would dump CC and go with PS or GIMP.
