I guess, what I love about it, is that it's accurate and at the same time it's inaccurate. I mean, that I have more control over the brush and especially over the paper, I can turn and rotate it as much as I want.
On the other side, since there is no "history"-tool like in photoshop and therefore it's nearly impossible to undo a brush line, I learned to be more free in outlining, allow myself more sweeping lines and more easiness. Art doesn't exist in only perfect lines, they sometimes make a work look lifeless. You know what I mean?
But I would never give away my tablet. It makes coloring and designing much easier! (:
