My favorite over the last few years is AK-48. I like it better than White Rhino. I'm currently getting ready to flower some Hindu Kush and NYC Diesel, dunno how those are, but they were recommended by a friend, so I thought I'd give 'em a shot. The Kushes are bushes (heh), but the NYC Diesels are still just seedlings, so probably end of the year before the Diesel is ready.
