Which solution (FEM or Momentum microwave) should be used for Patch antenna

I have designed multiband microstrip patch antenna with inset feed (for LTE) and I have used finite ground plane. When I am doing momentum microwave solution I am getting very poor gain and radiation efficiency. But when FEM simulation is done then results obtained are good. Can anyone please tell me the reason for this difference between FEM and momentum microwave. Also tell me which solution is better to use for my design?  Thank you
