Saying "x is the best ADC" is opinionated. It's up to the player's own skill to tell them which ADC is their personal best.

The only thing is, it's a general idea that Ashe is the weakest, though, there's players that can destroy when using her.

I, personally, have all the true ADCs, except Corki. My personal best ADCs are Varus, Ezreal, Kog, Twitch, Draven, and Vayne.

True ADCs are Vayne, Varus, Ezreal, Corki, Ashe, Sivir, Twitch, Kog, Draven, MF, Graves, and Caitlyn. TF is better off as an APC. And Urgot is more there to make the enemy ADC's life a living hell. Also, the four melee ADCs aren't true ADCs either.
