I draw on a small XP-Pen Star G430 Drawing tablet. (no pen display obviously) i've never tried seriously drawing something on mouse (i used to trace irl sketches on a trackpad though, ew) it just seems painful.
I also use XP-Pen Artist 15.6 Pro Drawing monitor that is bit expensive but worth the price for serious artists. this is one of the best rated tablets for drawing. This tablet work with PC and Mac too. The tablet is lightweight and has 15.6 HD display , Has a surface which is closely bonded to the display reducing parallax . support pen tilt , Pressure Sensitivity is awesome 8192 .I have found some good reviews from internet .
