Im planning on moving to California next year when i finish University? L.A or O.C? Help please?

So im From England and im going to move to California next year when i finish my degree. Ive always been attracted to Los Angeles or Orange county e.g. Newport Beach, Laguna Beach areas. I was wondering if anyone could help me out or offer any ideas on these areas. Any california residents or any body at all that could help would be brilliant. Cheers
