Trying to out-smite the enemy jungler for Baron/Dragon

Hello, casual plat 1 player here.

I main jungle and adc, and whenever I get the jungle role I saw the most important thing to do (in my opinion) in any scenario, is trying to out-smite the enemy jungler. There are junglers who are specifically built for this, such as lee sin for example, His Q can let him dash into baron/dragon and deal missing health damage and can smite right when he lands the kick. And if your playing a jungler for example, hecarim, who can't quite as well do that much "burst" as lee sin, can prove to be a problem.

So, in this case, would be best to make sure that lee sin is either at another part of the map, or dead, so that taking baron/dragon is guaranteed. I am just curious to know if there are other strategies in these sorts of scenarios that might be possible... Inb4 git gud.
