Congratulations on your offers! Regarding which university to choose, what you should prioritise is the area of study that you are interested in, which, from what you suggested, seems to be computer science. You have the option of studying the Bachelor of Computer Science at WSU which matches your study interest.
Additionally, keep in mind that your performance throughout your time at university, i.e. results + GPA/WAM is important irrespective of the university you choose to attend. Optimal performance can be beneficial when seeking employment opportunities during your time at university, such as internships (which enable you to gain work experience before graduating), as it can make you a more competitive applicant. Generally speaking, attending a particular university solely due to supposed superiority without prioritising performance/failing to perform to a high standard is not likely to be beneficial for the student.
I hope this helps!
