My take on that:
I see Analysis as suited for the "exploratory" phase, when you need to create new tables, graphs, etc... to identify insights, execution gaps, etc... or when you are validating the new data you are ingesting.
And I see Views for the second phase, when customer wants more to control the process, the evolution, the compliance, the implementation of the improvements... and/or when you need to provide a "tool" to execute
So, in a first project with a customer with average process maturity, I will show the results with Analysis. Then after identifying the improvements I will implement Views to control and manage the implementation of those improvements in the process.
Agree with Mateusz that looks like Celonis is putting more effort in evolving Views... looking forward for the Celosphere to get more info about Celonis roadmap in this and other aspects.
