Krita is good for art but not photo editing in my personal opinion as someone who is slowly learning to draw art as part of my many hobbies
Gimp is more suitable for image editing though I haven’t used it in a while because I just use pirated photoshop these days for photo editing
For someone who is new to gimp navigating it can be hard at first and the gui can be a bit cumbersome but as you learn the menus and use gimp those problems go away
