Mine would be as follows:
Tier A:
(1st) Dragon Breath / Dragon Claw
(2nd) Dragon Tail / Outrage
(3rd) Dragon Breath / Dragon Pulse
Tier B:
(1st) Dragon Breath / Hyper Beam
(joint-1st) Dragon Tail / Hurricane
The rest of the Dragonite movesets are not as good compared to the above. DT/Hyper Beam does less DPS for me because (i) HB does not have STAB and (ii) Hyper Beam exposes you to taking damage for way too long.
As for all the SW movesets, they feel too slow (and SW does not do STAB damage). The only exception to this could be SW/DC but it definitely feels inferior to the DB movesets and to DT/Outrage and DT/Hurricane as well.
Just from my own field testing, see what works for you.
