"To me, [he] comes across as far more knowledgable and grounded than Roberts. Alito has tons more judicial experience than Roberts did, and can refer back to his own decisions - of which he has hundreds."
IMHO I think Alito should have been chosen as the chief justice. Alito does, indeed, have more substance. It's said that he's the most experienced nominee in the last 70 years.
What a pleasure to see such excellence on display.
