I just went through this yesterday. I got Hurricane, but wanted Outrage. EDIT: Used another charge TM and got Outrage. Outrage provides higher DPS, can be used twice as much, and is the same power. While I understand Hurricane is a great counter for Machamp at this time, raid bosses will probably be rotated. For me I have found damage per energy use to be more important than the quickness of the move. Yes, I miss some dodges, but with 5 other highly capable pokemon it rarely makes a difference. Also I have two other dragon tail hurricane Dragonites which work great, but wanted a high IV, high CP one with Outrage. According to a couple different sources I use for moves, DT/O is the highest DPS moveset, and DB/O is second. Hurricane just has underwhelming power for a one bar, despite it being one of the quickest to use in the game. I am perfectly okay with outrage taking its time, and going back to spamming breaths.
I just powered it up to level 30 last night, so hoping to try it out today.
