DD Nite is ok, but in this fast paced meta, it's just asking to be revenge killed. Even at +2 it can be revenged if you run Adamant without ES, and if you run ES, you're going to miss out at hitting something.
MixNite is a terror. Nothing can switch in, and since Choice Band and DD is so popular, you may not even see coming.
AgiliNite is underrated, but I wouldn't use it outside of rain. STAB Hurricane with unpredictable coverage is the main draw.
BandNite is my favorite, but it's obviously going to be revenge killed as soon as you click Outrage.
I never seem to make mono-attack sets work. Latias, Dragonite, and Espeon all fail with me :(
I also Lol'd at Genesect being mentioned with every new PotW.
