Unfortunatly Lava is right, LeBlanc is a single target nuke while Sona is straight support. Thats comparing nuke to support, which are 2 different playstyles. Overall, LeBlanc is good in teamfights with double silences and a slow/stun, when your a premade team then you can have LeBlanc go for a certain target which can increase your chances in winning teamfights higher.
LeBlanc >=< Sona
I am comparing their power relative to other characters in their classes. Sona is the defining support character, there is no arguing that. I am arguing LeBlanc is the defining Assassin.
