What's Your Favorite JJ Abrams Series?

Tonight's premiere of Fringe got me thinking about creator/executive producer JJ Abrams and his pretty stellar track record on television.

In the past decade, Abrams has created or co-created four shows (Felicity, Alias, Lost, and now Fringe) and executive-produced two others (Six Degrees and What About Brian). Many of those shows had ratings success and/or significant buzz, and all of them (well, except maybe Six Degrees) had vocal fan followings. While we wait to see how Fringe will stack up, which is your favorite of Abrams's series so far?
