Now that I see that this thread was moved to the correct section, here is my two cents on this subject.
Think of it like this: You can have all the best equipment in the world, the next generation software and products, everything that you would need to create top notch quality music. But if you don’t know how to work everything then everything that you have is worthless.
Apply that to this situation. Even if your software or product is not the best, if you know how it works and how to use it you’ll have a much better outcome compared to someone who has no knowledge of it and doesn’t know how to work it. So with what 1337al said, if you like a certain program then stick with it. It doesn’t matter how much you spent, it doesn’t matter how sophisticated a program is, if you don’t know how it works don’t try to use it. Stick with what you’re comfortable.
I’m actually switching over from Photoshop to Corel Painter for this very reason. Even though I have used Photoshop a lot, I feel that I am just not in my comfort zone as I am with Corel. I can do much more in Corel than I do in Photoshop using my own skills and style. At the end of the day it isn’t how much you spend, it’s how much you’re comfortable and how much you know.
