There's a lot of mud-flinging in this thread about the superiority of this software or that.
Frankly, this is all BS. All of these softwares are capable of producing professional results. The difference is made by the user, not the software. Learn one of them; any one of them. Learn it well. The individual choice in the end is just a preference, but does not determine quality. You do. Thankfully.
(That's a bit like modern cameras. They are all great. They are all capable of professional results. The individual choice in the end doesn't matter.)
