Ultimate or Premium 360 or both?

Hi

I seem to have active subscriptions for Premium 360 and Ultimate.

Are both of these necessary or can I ditch the Premium 360 (my original subscription)?
Thanks

Norton Utilities Ultimate is a standalone service with its own set of features and tools not included with Norton 360.
Norton Utilities Ultimate is a newer, more advanced version of the Norton Utilities Premium.

Norton 360 is needed. IMO
Norton Utilities Ultimate is optional. IMO
