Fast and frail.
It has Mewtwo levels of DPS but only a total damage output anywhere between a third and half of what Mewtwo can do. It's far and away the fastest non-legendary option, unfortunately its typing means it takes at best neutral damage from any given attack. This coupled with its low defenses don't help its case for longevity.
I wouldn't be worried about gearing up for Machamp solos at the moment since it's not an active raid boss due to the Valentine's Day event.
