Both good. Like I said in another thread, I really do not know what people expect for them to say either were a poor show. Expectations way to high. On the whole your ratings are fair. A 9 or 10 show would be new hardware announcements and/or megaton reveals which rarely happen.
My scores
MS: 7/10
Sony: 8/10
Sony in my opinion showed off more exclusives that appealed to me. Plus most of the multiplats they showed had some sort or exclusive deal with it while MS' didn't.
