the usa export to emirates arabe unis the best version of f16 ( block 60)
Because the UAE paid billions to develop it, but even those F16s are little more than target practice against F22s.
China exported the F7PG to Pakistan, which was much more advanced and capable than the J7s the PLAAF was flying; but China never exported the J8 despite strong Iranian interest.
Off the shelf export weapons will almost always perform worse than domestic versions.
