LMU vs. USD

PLEASE HELP. I am absolutely so torn between these two schools. I definitely want to go to a fun school that still has strong academics. I am a communication major at LMU and International Relations major at USD. I feel like LA would be much more fun to be in then San Diego but then again I know LA much better then San Diego. So torn please help. Which one would be better for an overall exciting and fun college experience?
