Here’s the thing… Just like photography, there are a lot of different types of “Photoshop” it really depends on what you want to do with photoshop. You’re going to find people who focus on graphic design, you’re going to find people who focus on creating digital art, you’re going to find people focusing on model/body retouching, you’re going to find people who retouch products, you’re going to find people who deal with landscapes. There is overlap in all of these but a good one focused on what you want to do is going to be better than a very good one focused on something that isn’t what you want to do.
