Difference between Momentum Microwave and FEM Simulation

I have created layout and simulated in ADS momentum. My circuit/layout application frequency is 0-30GHz, so which one among Momentum Microwave and FEM Simulation will produce accurate results for the above frequency range ? Because results are not same when we compare both (for example S21 is Almost double in FEM as compared to uW). 

- While performing Microwave simulation for better accuracy I have kept cells/wavelength  to 150 also I have selected "Edge Mesh"

-While performing EFM simulation I have kept delta error to 0.008 and Max.Number of Adaptive passes to 40.



Thanks in Advance
