One thing I noticed when running 17's is the car feels much more responsive in turns. Would this lead to better times or is it still a matter of rotating weight?

Yes the test was done by Tire Rack and Grassroots MOtorsports. But that doesn't mean it wasn't biased.
But yes the car with 17s will feel more responsive cause the sidewalls are stiffer. The same feeling can be felt with higher pressures in 15s.
