Hover involves an environmental condition called “Ground Effect” where the air stops acting like a fluid, and it gets a springy property. The computers have to deal with this and make automatic adjustments.

Flying a helicopter, or any vertical lift craft, involves more degrees of freedom, and the pilot has to manage them separately. Your toy drone uses an onboard processor to eliminate some degrees of freedom, but that reduces the operating envelope.
