DT/Outrage has slightly higher DPS than DT/Hurricane, but it's not just as simple as Damage Per Energy. Outrage has 220 damage per 100 energy, while Hurricane only has 110 damage; however, Outrage's cooldown is an extra 1.2 seconds per use. During that extra time spent using Outrage, a Hurricane Dragonite will be using Dragon Tail.
In a full damage cycle with Outrage you'll spend almost 8 seconds in cooldowns (7.8 seconds) versus only 2.7 seconds of cooldown with Hurricane, which is basically enough time for 5x Dragon Tail, essentially another ~90 damage in addition to the 137.5 damage (with STAB) from Hurricane. So, in that cycle you're looking at roughly 227.5 damage.
Compared with Outrage, you are dealing 275 damage but you are gimped and unable to dodge during those long cooldowns (each is longer than Hyper Beam).
The above calculations only take into account the damage dealt during the use of 2x Outrage and don't represent "cycle DPS," but it's meant to illustrate the difference between DT/O and DT/H. One deals more damage, but you'll be stuck in cooldowns much longer.
