Highest skill-ceiling-in-normal-play Wilds weapon?

Thought this would be a nice counterpart to the "easiest weapon" thread from earlier.

We're far enough out from launch now that people have a general idea of the game. Obviously, it's a Monster Hunter game, so every weapon has a very high skill ceiling and supports deep and intentional play with lots of space for optimization, particularly in speedruns that try to drill down into "the perfect run."

However, I think that "perfect run" gameplay doesn't really resemble what most of us are doing when we play Monster Hunter. We do cozy hunts, run some hard hunts to sweat a little but don't take it too seriously, hop in on SOS flares for mats we need, etc. The monster aggro switches, it jumps around, you have to improvise and adapt. It's less about the single runs where everything goes right.

In that context, which weapons do you think have the largest gaps between a good player and a great player? Who is autopiloting the least in their normal rotation? What weapon supports—and rewards—the most complicated decision-making?
