NL is a classic but Afghani can take anything. Higher PPM of nutes, bigger range of temperatures, all kinds of stress, and more resistent to insects/mold in my experience. But more of a knock you on your ass high instead of the lighter NL. The smell will also be much more of an issue then NL, which has barely any odor. PS. The Afghani should be the tight bushy one and the NL should be lankier.
