I have noticed Alito has no notes, which says quite a lot considering his 15 years of rulings on the 3rd Circuit. Just as impressive as Roberts, if you ask me. He has more experience than Roberts too. I think having been a federal prosecutor is a big plus.
Someone mentioned that Alito has the most judicial experience of any SC judge/nominee? (except for one in the early 20th century) in the history of SCOTUS.
