I am in the middle of evaluating different photo editors. I use Capture One Pro for almost all my photo editing work. It does a great job and in most cases I don’t need any other program. But Capture One Pro can’t do more advanced work like merging multiple exposures or frequency separation. Adobe’s Photoshop is of course a very popular choice for a lot of people. I’m not going back to Adobe since they introduced their “creative cloud” concept with a monthly fee though. If I pay money for software I want to own it. So Photoshop is out of the question for me. There are a number of other candidates to choose from.
