GIMP alternative?

Literally just for the sake of interest I downloaded the version of the gimp under Windows. Surprised by the presence of functions very similar to Photoshop . Poyuzal, I came to the conclusion that you have a task in retouching photos, photo corrections, then the software is quite suitable. Naturally, it is too early to talk about friendliness and usability, but think about it! 7 meters crammed a huge amount of functionality, and it works not under Linux, but under Windows. Rulez. What is not pleased? I tried to export data from under cs2 to the hymp, it showed a fig to me, which is a pity. If they finish it, it will be very good. Can someone meet a quality alternative to Photoshop?
