Migration from Office 365 to Active Directory Domain
But if you are talking out of the box, E3 or less only then yes, I would not recommend cloud only :).
ChrisWebbTechI think Chris is on the right track. There are certainly options to either approach but all the future development is going into the predictable recurring revenue models that cloud is giving to Microsoft, Google etc..
To clarify one item mentioned earlier you certainly can join/register Windows 10 machines to the Azure service included as part of Office 365 Business Premium. I have done this numerous times. It does not give you all the control an on prem would but you can login with user Office 365 accounts and do some very very basic management (recoverable bitlocker key for example). Full Intune certainly expands on your control options and as Chris said is almost in parity with on prem.
The challenge you have is planning out a path that provides a smooth migration with minimal disruptions for your business. That is probably the bigger picture over if one control methods has which bell or whistle for IT. They both provide a way to manage depending on your skill set but in the end one will be sun setting and the other will be getting improved over time.
