My brother use Chuwi Hi12 for painting and different sketching. One day I tested it and can say it is not bad. Here is a drawing test: https://www.youtube.com/watch?v=x9e4c-2IQaQ
However, as for me, I am owner of iPad and I am not professional painter, but it seemes to me more comfortable and convenient for drawing. If you are not a big fan of apple or you don’t like the price of iPad, I recommend also check Microsoft Surface 3 tablet with stylus: https://www.bestadvisers.co.uk/best-tablets
Of course, these tablets can not be compared with professional tablets created directly for painting, but this is a good simplified alternative, if you don’t want to use PC.
