My impressions so far:
Trevor Noah totally nailed the new style, swift jokes and editing. Quality YouTube. 
Stephen Colbert had great fun with his family, slow pacing, natural and hilarious.
John Oliver keeps the same routine, witch worked perfectly without live audience.
Jimmy Kimmel just looks and sounds miserable without audience, stops for laughs that don’t come, reads unconvincingly and without energy from cards, and for some reason his collaborators just feel the same.
