I can say, that we have four kinds of users:
1) number affine users that are happy with their static number graveyards, tables and diagrams etc.
2) users that like to "work" with data, they like to use cubes, as they can move around dimensions.
3) Dataminer, that use tools like SSAS etc. to work on the data given.
4) users that want a much more aggregated view on things. They mainly need short tables, Charts, Gauge, Indicators etc.
Group 3 is looking for tools to visualize their results and often are looking for tools like tableau.
Group 4 tents to favor the tools that a shiny and interactive and can be used on their tablets
As I like to keep low/reduce the "faces" to the customer I would favor a M$ integrated tool like PowerView, to satisfy Group 3/4.
However as PowerView is still depending on SharePoint I might not be that lucky.
