Analytic view or Calculation view

Dear Experts,

I have a scenario where we used 2 analytic views A,B and on top of them there are 2 calculation views C(on top of A) and D(on top of B).

Calculation views are created just for aggregation purpose.

In re-designing above scenario, Will it be good to use only calculation view including all the things from Analytic view and use aggregation as in previous calculation view?

Is there any additional benefit in terms of performance or etc. if we build Calculation view on top of Analytic view just for Aggregation purpose?

Thank you for your help.

Regards,

Raghavendra.
