I have been using both Procreate and Tayasui Sketches for a number of years, and more recently Adobe Fresco. Procreate is an industry standard for many reasons and I have used it for preliminary sketches, illustration elements, and final projects. Tayasui Sketches is superior in its watercolour and painting effects and I have used it for illustrations and for design elements where I want an artistic effect. Adobe Fresco has been a welcome change, having an app that I can integrate with the other Adobe programs I already use.
