Well. This is opinion based, but here I go.
I have an Intuos 5 Touch. That is my second tablet. Cool talblet. But I almost never use it.
I only use it from time to time for photo retouching, like removing imperfections on a portrait skin. That is it.
My workflow can be non standard, becouse I do some, what can be considered photo retouching and compositing, inside a vector program. (Like this: Creating an implied floor with light
The reason I do not really use it:
Well the point is that on a drawing tablet you need to keep the pen floating above the tablet. Any shake is recorded and a click is made either by lowering the tip to the pad or using a secondary button on the pen. When I move my muscles it can vary a little the intended position.
I use a very good and sensitive mouse, on a really clean surface. When I have it on the right position, the click does not move at all the pointer position.
For cuting a photo, inside photoshop for example, you can need that kind of precision, so it is relative if you need it for photo retouching.
I like that precision. Thoose are my needs.
Do I like it?
On thoose rare ocations I use it, yes. For my everyday workflow, no. But I like the idea that some day I will be more digital painter.
A Tablet is not necesarly for drawing
In my case I feel it that it is not for drawing, but for "painting".
Retouching a photo more freely, like hunting imperfections can be painting.
So it really depends on your workflow.
