Thanks for being a part of the GoDaddy Community! You can move your Managed WordPress site to Cpanel following the steps in this guide. The primary difference between cPanel and Managed WordPress is Managed WordPress handles the WordPress install, daily backups and software updates for you. If you are unsure as to which plan would best fit your needs I'd recommend reaching out to live support, they can explain to you your options based on your needs. Hope that helps!
