Master Data Views - Analytical Dimension vs Analytical Cube

Hello SAP experts,

I have encountered two questions during CDS view modelling in S/4HANA Cloud that I hope you can help me with.

In the Custom CDS View app there are two analytical scenarios available. I am asking myself now what are the implications by choosing the two scenarios in the reporting?

The final report looks the same in the tests that I have done so far.

Additionally I am wondering what the implications of associating Master Data Views are in the reporting later on. What does specifically change if I choose other Master Data Views instead of the two that I have selected in the screenshot above?

Thanks in Advance!
