i like flat bars too, and think they are easier to do long skids with, but risers offer fore/aft adjustability without changing stem, both are good for quick turns, ducking through traffic.
Risers are very good for skip stopping without moving too much.
Flat bars look better when done right, to my eye. Not as sweet as nitto 123 drops, but I think risers only look good
in a throwback bmxish way. I have them now, for tricks, and for my ****ed nerves in my right hand, but always think that
nothing beats Cinelli NJS drops, or Nitto Cromo 123's for looks.
