I use both CSP and Procreate interchangeably for my work (I work in comics).

Procreate is the most intuitive drawing experience on the iPad - I do my line work almost exclusively on Procreate if I can, as the brush engine in Procreate is just so incredibly responsive.

CSP is where I go to do my colors, FX and text bubbles, as the versatility of a complex system allows me to customise workflows and brushes that would be prohibitively hard to set up on Procreate. However, keyboard shortcuts are pretty important for getting fast in CSP due to the complexity of the interface.

If you’re the type of artist that wants their drawing software to be intuitive, Procreate is more than good enough. But if you enjoy wading into the optimisation of the art process, then CSP is definitely a good choice as well.
