User blog comment:N00bpl0x/Why are some ADCs considered superior to the others/@comment-60764-20130701182811/@comment-11504220-20130703103012

Draven has to continuously catch his axes in teamfights to maximize damage, which isn't always consistent with the best place for an adc to move to. This also severely gimps his kiting ability. On top of that, his ult shouldn't really hit anyone past a certain distance. Past a certain elo, just about everyone will evade a skillshot that comes from half a screen away.

Compare this to Vayne, whose attack animation and roll is perfectly suited towards kiting, as well as dodging cc, her knockback hits much harder against a single target and can potentially stun which means it is much more effective against gap closing assassins, and her ult gives her incredible dueling ability, even against multiple opponents, especially when the stealth roll is saved for juking imminent threats. This is without even taking her true damage into account, which is a relatively small percentage of her total damage output, but completely makes the difference against heavily armored champions.

However, since as far as anyone here knows, either of us could be noobs who don't know anything, I would point to the fact that literally every dominant pro ad carry agrees that vayne is the better adc; no contest.
