The following result is obtained by our Expert's opinion:
iPad OS still lacks many of the complete desktop features, you can't rely on iPad for complete functionality even if it is iPad Pro 2020. Though Apple claims that it contains all features and power that a personal computer possess but practically many important features are still missing like XCode and other complete packages of big software from Adobe and other large developers. People buy PC especially for running such software efficiently.
iPad can't replace your PC in many cases.
If you are an artist and work with artistic stuff like illustration and other or portability is the priority for you then iPad should be your first choice.
In overall other cases, MacBook Pro is definitely a better choice than iPad Pro.
