I would like to point you to another Paintprogram.
As you wrote that you would like more Varitations
with your Brushes.
Take a look at "PaintStorm Studio"
, i think it would
make you happy.
For its price it is about $ 20 (it is only a one-time fee,
so no subscription like with Photoshop) it is very powerful
painting program with a very good brushengine.
It has also a Stroke Stabilizer like Photoshop.
Whereby Lazy Nezumi has many more uses
than just to stabilize a Stroke.
It has also a Demo Program with 30 uses, so
you can try it out before you buy.
Will work on PC, Mac and Linux and there is
even a Version for the iPad.
