I am seeing inconsistencies between these 2 sets of logs. For example, Azure AD shows me that Office Groups were recently created and these activities don't show up in the Unified Log in the S&C Center. The S&C Center is showing me that the Site Collection and Team were created, just not the associated Office Group. This lack of consistency is concerning and requires me to look in 2 places, which totally defeats the stated purpose of the Unified Logs.
I also notice that the presentation of the attributes for each activity is much easier to understand in the Azure AD log and I would like to request that the S&C logs adopt their model.
One specific example is that Azure AD log shows the Actor that initiated an event (service name and the UPN) whereas the S&C log shows a service account instead of the users UPN which makes compliance verification much more difficult
