OG Kush, Purple Kush, Afghan Goo and Sour Diesel are solid choices. They all have a decent flavor when smoked. The Purple Kush has a slightly better flavor but is not quite as stony as the Afghan Goo or the OG Kush. The Sour Diesel is one of the strongest sativa based plants available the high is different but you don't have to think about it. If you can get Lambs Breath or Lambs Bread do so. It was Bob Marleys favorite for a reason.
