Main support or mid or jungle?

So I've been playing league for almost 4 years now. I never had a 'main' role. I pretty much have played every role to a decent standard. I Finally reached diamond and I really want to start to main a role. Top lane I don't find as exciting to play as this cinder hulk is just stupid. I find jungle as a alright role to main, however I feel as a jungler I won't be able to make the same plays. Don't get me wrong, junglers do make plays early, but nothing to compare to like a mid Zed outplay. I find a lot of success mid, but it's a very contested role. I really don't like marksman as there is too many factors too consider playing that role in my opinion. Perfect farm, positioning (etc). Lastly, support in my opinion is very fun, you get to make awesome plays and almsot be a second jungler. But it's tough to carry, especially when behind. I just want to hear your opinions of what role you think (out of those 3) is the best to main.
