Like, you go in to Krita thinking "Ah yeah, this'll be like Photoshop but worse, for the people with opinions about software licenses to pretend to like in the name of freedom or whatever," and then you give it five minutes and it just completely knocks your socks off.
Example, built-in timelapse function. Press one button (one button!) and it'll go "aye aye captain" and save a snapshot of every change and then make it into a video of you starting with a blank page and going stroke by stroke before ending with whatever awesome thing you made.
Brushes? Brushes out the wazoo! Watercolour brushes! Proper physics and stuff! Stroke with the very tip of the stylus and it just moves existing paint and water around, press harder and the paint comes out 'cause it's thicker and in the middle bit of the bristles!
All those layer blending modes that Photoshop comes with? Krita *starts* with all those and then goes "Heh, cute," and gives you like forty more better ones.
Krita doesn't compete with Photoshop, it *embarrasses* Photoshop
