Yeah, Jayce was my go-to guy for top lane in ranked, however, I started to learn how to play Riven. Let me just say, that if played effectively, is probably one of the strongest laners in top lane.
So for all you Jayce lovers out there who haven't tried Riven, I'd do so. After you get used to her mechanics, she is super fun. I mainly only ever played top as Jayce, though I played him mid as well. No other top laners really appealed to me like Riven. She has ridiculous trading capabilities and you can usually (and probably should) eat the other top laner super early.
