A couple of years ago I got an iPad 3, and shortly after I got the Adonit Jot Touch, a very unique stylus designed for iPads which have a fully featured digitizer in the stylus itself. When paired with a compatible paint app (I used Procreate), it's very comparable to drawing on a wacom tablet screen.

This is the first picture I have drawn with it, mainly just to test the capability of the stylus.

Note that I have a Surface Pro 3 now, which is miles better then this.
