You're missing the point. All I'm saying is that over time, Boomburst's higher accuracy (and higher base BP) gives it higher damage output. Sure, there may be battles where it never misses. It's also pretty likely that there will be battles where it misses two or three times in a row.The confusion chance doesn't need to be reliable.
You're not using both moves 100 times, you're using either one less than ten times per battle. But yes, Hurricane has low accuracy.
Draco Meteor + Hurricane. Can't go wrong. Have you tried U-turn?
Hurricane hits a little harder... when it hits. But from battle to battle, Boomburst will end up doing more overall damage simply due to its reliability. IMO, this makes it a better pick.
Hurricane definitely has a place, particularly for rain teams that raise it's accuracy to 100%, or extremely lucky trainers ;). But basic probability indicates that Boomburst is theoretically the superior move.
