What Would You Suggest I Use?

Hello!! I have been doing Episode art for quite a while now on my IPad Pro with the Apple Pencil on Ibis Paint X, but I don’t really know that it allows me to do everything I want to, so I am thinking about doing art on my computer/PC and using my IPad as a drawing tablet.

Does anyone know of any good programs that will let me do this? (that don’t have a virus)

Do you think I should continue on IPad or try on computer

Thank you!!

Does it work on computer?
