I have very limited IP, and I don't gain much from week to week due to my play time, so I'm looking for a definitive jungle to buy and learn.
Cho'gath used to be my main top, but I stopped playing for a while, and since coming back just really haven't played him much. Nothing against him, I've just been trying out and collecting other champions. I personally don't think his q is reliable enough to get consistent ganks. You basically throw up a warning flag to whomever right before it goes off so they firstly, know you're there, and secondly, know to get out. The effect doesn't last long enough nor is it reusable quick enough to keep them from running back to their tower imo. I could be wrong though as I'm not by any means an expert, hence why I'm coming here to ask about a Jungler to buy and learn.
There are some champions that are the best at what their role is, for instance, Jax is seen as the best duelist. I'm asking who's seen as the best jungler. This is someone who will be able to gank consistently and effectively, duel against an invading enemy jungler, and clear fast.
