There's this new player in the art software category. I just installed it, it is really amazing. It's fast, as in drawing the strokes on a tablet with a stylus is much more responsive with this program vs. photoshop, clip studio (which is what I currently use). And it has this "infinite zoom" feature, which is essentially vector graphics for a program like photoshop. So it combines features of Illustrator, photoshop into one program, which is what the clip studio tries to do a little also. What makes mischief stand out is the touch-friendly interface...very simple layout (you don't have to hide/unhide the sidebars all the time, or get those artdocks), and it supports multi-touch gestures.
I really like the idea of zooming in and out and not getting any pixelation. Also, a unique feature...the brush size doesn't get smaller/larger as you zoom out or in. it stays the same size. Why is that cool? Let's say I drew a tiny tiny circle...now I can zoom way into the circle and draw yet another tiny circle inside it without changing the brush size and the thicknesses are relative to the zoom.
