In my opinion, I think it would be who you are most comfortable with. I was a top lane player and my champion of choice was Fiora. Last season when I was playing League Of Legends, I peaked Platinum 1 and ended Platinum 2. I could solo almost any top lane beside Pantheon because I had so much experience with my champion however, I truly felt that the victor of the top lane was depended on the ganks received. You should find a jungle main to queue with you for the best chance. I have played for about 2 years, I somehow managed to get P4 my first year after switching from Dota 2 but I still have a lot to learn. ^-^
