ESJeffL , good question and I get this a lot, let me give you my elevator pitch, DM me if desired and we can talk more.  Short answer to your question.  I like to think of the value of W365 synonymous to the value customers got when migrating from Exchange on-prem to Exchange online.  With Exchange online you assign a license and in minutes a mailbox is created, with Exchange on-prem there is so much overhead for setup and massive amounts of maintenance.  W365 is a SaaS just like Exchange Online, made simple and made to run in the Cloud.  The value is simplicity and speed.  The time to deployment is super easy with W365 as I explain, 1 license assignment and 4 questions so customers already using Intune can adopt it super quick.
