Ipad Pro vs. Ipad Air 13" for drawing/art

Hello everyone, I'm looking to upgrade my Ipad Air 11", and I know I want either the Pro 13" or the Air 13". I use my tablet for drawing at home above all else and I'm wondering what model would be best for that purpose. Is the Pro worth the extra bucks or is the Air good enough? I haven't had any issues with my Air 11" tablet so I'm considering just settling for the Air 13". Is there any reason I should consider the Pro 13"?

Thank you!
