The AA-11 (R-73, Archer) is more advanced than the AIM-9 (up to the M version), the Python 4 is considered to be even more advanced (manouverable, better target acquiring range etc.). Although the Python 4 is not equipped with TVC, it uses a very advanced aerodynamic design, which makes it at least as manouverable as the Archer. In any case, when comparing the Python 4 and the most advanced version of the R-73, the R-73M2, you can see that the performances of those two missiles are very, very similar.
Here is an interesting diagram:
It compares the R-73 and the R-73M, you can see that the M version has a larger target acquiring (60 degrees off center) zone, and a longer range. The Python 4's "no-escape zone", BTW, is at least 60 degrees off center.
