Reliable top champions?

I'm looking for another toplane pick, a reliable champion that can handle itself at most stages in the game and doesn't need to be fed to be useful.

So far my best pick is Poppy, she's tanky, splitpushes well, she might struggle a bit early, but after her first back she's usualy tanky enough to survive anything. She's useful, etc. And as long as i ban Nasus, i'm fine.

I've tried Illaoi and Yorick, but both can be countered pretty hard, and their utility is very limited.

I'm mostly looking for a tanky champion.

I've been thinking about Shen maybe? He can help his teammates with ult, can splitpush well and seems useful in a fight.
