Momentum RF mode for microstrip circuit

Hi,
I'm currently doing some microstrip circuits dividers. When I simulate the circuit on the Momentum microwave mode or on HFSS I obtain the same result. When I switch to momentum RF mode the result is diffrent. Which mode should I trust in Momentum?
Thank you.

What is your frequency ?

The frequency is 60GHz

You must use MW Mode.
RF Mode can be used below 1-2GHz and does not include Radiated Surface Current.

Thank you very much.
