5.2.4 or 7.2.2 atmos setup?

[JK Saabh]

Hey folks,
I'm thinking of getting the Denon x4100, which (if paired with an external power amp) can power nine channels. I already have a 5.2 setup, and I wanted to know your recommendations on whether to go with a 5.2.4 or 7.2.2 atmos setup.

Thanks

7.2.2 is the best for use.
