I have to agree. The current dynamics in Gimp, compared to MyPaint, are 
really ugly. I switched to MyPaint for drawings half a year ago and 
sometimes i try to use Gimp more or less the same way (for painting). 
But usually I'm scared away in not longer then ten minutes and happy to 
use MyPaint instead, even for small tasks.

The things that where most annoying in Gimp are:

1. There are no real presets for brushes. Every time you want to use 
another type of brush you have to reconfigure it again for the task. 
This is a time killer.

2. Even if I take the time to configure a "brush" I only have very 
limited options and flexibility. Not much result for the effort.

3. Gimp is really slow at drawing. I don't know what it does in the 
background, but the brushes feel slow, especially with a tablet. Got 
even slower with soon to be 2.8 compared to 2.6.

Overall I might add that Gimp inherited the worst possible combination 
for someone that wants to use Gimp for painting. As a painter I'm used 
to switch from one "tool/brush" to the other to get the desired effect - 
the same effect, immediately. Additionally I want to fine tune my 
presets, store them and reuse them. Nothing of that is possible, going 
way against the natural work flow of an artist.

For me Gimp is a rusty Swiss Knife for images, but not a drawing program 
any more (the standards improved). Hard words. I know. But this is how I 
see it. Gimp should really concentrate to improve usability by making 
things easy/quick to use. For example: In MyPaint i can switch to my 
previously used brush/tool with one click or press on the tablet. In 
Gimp my first action is to scroll to the brush list. Selecting it by 
mouse click, adjusting the parameters, restoring the dynamics, ... and 
after 2 Minutes I have roughly what I need and forgotten what I wanted 
to do with it.
