The best sativa I tried was some lambsbread (actually sold to me as "lambsbreath") somewhere in the 2005-08 years. It was the first real sativa I tried. Pretty psychedelic. Went on a hike and found all these badass rocks and took em home. Looked a little less interesting the next day, lol.
Favorite indica would be deep chunk. Still as good as ever. Lovely stone.
