I have the program. It is mainly a vector based program. How it compares to photoshop, I can't tell you because I don't have that one. I do have PSP Studio. I recieved the program at the end of Feb. and still have alot to learn. I have enjoyed learninfg more about vectors. It does render things much faster than psp and I can put a page together very quickly ( as quick as the idea comes lol). Now brushes do work differently, altho as I said before I have more things to learn. If there are certain specifics you want to know ask and I will see if I can answer them.
