There are different styles from what Ive heard. USYD is more theoretical, philosophical. UTS is more cutting edge and more connected with local architects. USYD apparently is more practical?? Not sure about that one.
I went on an Architecture summer school at UTS. It was alright... impressive to those who have not seen such design processes before like simple laser cutting. I liked that they gave us a tour of some firms and their offices around Sydney and we saw how architects actually work today. But I think Im inclined towards USYD as I am more theoretically focussed. I like to thing about why its designed in a clever way etc.
