KFX is light years ahead of Su-57. Comparing with AMCA, let's wait for HAL/ADA to roll-out the first prototype, but imo both aircraft be somewhat similar, obviously, both ver be inferior to the SFC version, where they paint the whole aircraft with RAM coating.Kfx is inferior to our amca better off buying the su57 then. Kfx is junk. We could even go for the f35 if the situation becomes that bad..
But as we not going to buy KFX, for sure. So comparison is useless.
