I feel like he's a lot stronger top lane because he actually gets a dedicated lane of farm and is guaranteed to hit his early power spikes.
I've laned as him against riven/renekton/yasuo so far. I crushed the riven into dust. The renekton lane was hard but I went deadman's plate early so he couldn't instagib me, survived and outscaled him. The yasuo lane was annoying as hell but I had a good jungler that game. I got caught level 1 and yasuo got the first blood, but I killed him twice in lane solo and 3 more times with lee sin's help.
I had a lot of trouble playing him into that yasuo's team comp, even though the other 2 games were perfectly fine.
They had: Lissandra, Ekko, Yasuo, Ezreal and Vayne. It was incredibly difficult to get picks on anyone.
