The last Jackie Chan film I thought he was really great in was Police Story 2013, although it's not really a "typical" jackie chan film as it's quite melodramatic rather than comedic. Still, he's in decent shape back then, and the younger generation he has in the ensemble are competent, so the stunt work is excellent in imo.

A lot of his crossover Western releases shifted their focus to just a small number of high profile set pieces (think the bamboo scaffolding scene in Rush Hour 2). While impressive, this meant less time was spent on intricately choreographed fight sequences, which is what I personally really dig, and Police Story 2015 is the last one I remember with a healthy balance of the two
