One big difference is the lighter weight of a 2 stroke engine. And that weight is removed from the top of the engine. This lowers the center of gravity in the frame.
So it's more agile. It makes the bike more "flickable" in tight situations, and easier to change trajectory even at speed.
Displacement closer to 300cc is supposed to increase low end torque dramatically. But you can do that during a top end rebuild (easy job on a 2stroke).
I am going for it. It is just a matter of when. I could do it today but working on banking good will
So I will sell one bike, or at least promise to. Getting it listed for sale locally should be sufficient
