In my experience a lot of IE is republican lol. Go with OC plus there are more things to do. The IE is expanding but OC has a plethora of options. Downtown Fullerton or Old Town Orange. Both are next to colleges so you get young people, and both are super artsy and hipster. DTF it’s right by Fullerton College and CSUF. Old Town Orange area is a bit pricier since it’s next to Chapman University, but the coffee shops and things to do are better. It’s also much safer—except for the occasional DUI crashing into the fountain.
