Trying to find myself a new campus

I am going to be an incoming junior in college, and unfortunately I absolutely hate the campus I am on. I need a new environment and I want to transfer to a different school which is good for C.S, has an active campus, and will not be too difficult to get into. So far I plan on applying to ASU, University of Arizona, and Purdue for Winter 2017. I want to know if applying for Winter 2017 will give me an advantage since their will be a smaller pool of applicants. I am also a California resident. Would that work in my favor since I am out-of-state? Also how much does ethnicity play a factor in admissions? Thanks for your help guys. Any advice is appreciated :>
