Hey michealjjj
Congrats! Those are excellent schools- but very different. Go to Archinect.com and browse the discussion forums- there are a lot of resources there comparing the two.
I just met some of the professors in LA and the program sounds really interesting, yet very independently driven. The work is innovative, unorthodox and highly idiosyncratic.
AA on the other hand is very similar to US programs- you will be working in groups and assigned projects. It sounds a lot like UCLA's program.
Let me know if you want to chat more...
