The tablet in the 2019 version also allows you to draw a freehand sketch that automatically transforms into a classic sketch as if it had been done classically with lines and curves and circles. I tried, it's not bad at all, to make a drawing concrete for a client. (at the client's place it sounds a bit geeky but it makes things very concrete) :-)
If you absolutely want to do freehand drawing, I could only advise you to turn to graphic tablets.
Personally, I've been a big user of the xp-pen Deco Pro graphic drawing tablet for a long time. High-precision tablet for image editing, freehand drawing and other graphics applications, Comfortable, thin and light stylus, battery-free operation. Sensitivity to tilt and pressure.
