2010 Acura TSX V6, Supercharger or Turbo? Are there any other parts you would suggest?

Which would be better for a 2010 Acura tsx v6 3.5 liter: turbocharger, or supercharger? and what company? I know there are no kits out for it yet (i think).. but I would really like to find something to give it some more power. Thank You!
