I can see that Denison starts you in with the foundations of CS and computing and quickly takes you to an advanced level. It seems like the courses combine more topics together. Trinity has more courses because the topics are separated a little. I don’t know if that means that topics will be covered in more depth than Denison’s courses or not. Overall though, I feel that they will offer you the same quality education and the same knowledge of CS. Now, it’s down to fit and financial.
Good luck!
