I agree with @samphil098 that Rutgers is better ranked than Rowan for Computer Science. See Rank NJ Colleges - Computer Science Major - College Search & Selection - College Confidential Forums - Admissions Discussions and Threads
However, if Rowan is significantly more affordable to you and if you like the campus, then I think that it makes sense to pick Rowan as I suggested a while ago.

Did you get accepted in the Honors College at Rowan?
