Research: List of top 50-100 features considered best in class spatial computing

Hi,

I am looking to get some web research help to come up with a list of the Top 25 - 50 features/elements of an Operating system & of an SDK for a "best in class" spatial computing / AR device (e.g, Magic leap 1, Hololens)

For example: SDK is composed of
API(s)
Documentation.
Editors.
Libraries.
Run-time and development environments.
Compilers.
Debuggers.
Drivers

Key would be to create a list of features related to the components that make lets say would make Magic Leap 1 better than Hololens and vice versa.

Then do the same for the operating system (come up with another Top 25-50 features)

Thanks
