Thanks. The main idea is that TK can fight any other JG, so no real JG counter if TK maintains same pressure. His ganks are very hard when ghost or ultimate is available.

TK also usually counters or does very well against melee top laners such as Darius, Irelia, Fiora, etc.

TK isn't so good late-game because he gets outscaled by adc+peel support, AOE mages and it can be hard to engage highly mobile comps.
