PLaAF is way ahead of the IAF. You cannot talk about LCA as well. It's an average performing aircraft, probably equivalent or less than the JF-17 if you can compare the two, and not headed anywhere for production for another 10 years at least by which time the technology will be outdated. JF-17 will be inducted within a year in comparison with plenty of scope for upgrades. Another point is that the JF-17 is developed from the same era technology as the Mig-29, so you might expect it to be performing at a higher level than this.
