The difference between these two paint program is that Painter tends to mimic natural medium and produce art like results while PS is meant for image processing purpose such as preparing image for print matching, find tune colors for various applications and file format. Notice a lot of 3d artist prefer PS is because of its straight forward tools, offset image for seamless tiling, snaping accuracy just to name a few. Often we can't affort both programs so PS is more practicle for multi tasks in a multimedia society. Unless artistic expression is more important, then Painter would be best.
