try to convince me to use gimp

I have similar problems with GIMP; as it stands, it still has the capacity to animate at all, compared to PDN.

GIMP also does this thing when tablet drawing with aliased art that makes all your lines gross and wiggly, too. It's like it's only built for antialiased art.

SAI in my opinion is better for drawing, PDN is for image manipulation, and GIMP is for animation. Photoshop is the warlock buffalo that, when tamed, allows mastery of all three.
