I dont think the last exercise really was meant as a test of russian aircraft against US aircraft.
I agree that the US aircraft were crippled in the last Exercise. But we cannot look too much into it. It was the first exercise in many decadesand both sides did not field fully equiped aircraft. US probably underestimated IAF and Indians were more interested in testing a real life encounter which is likely to happen with Pak which does not fly AWACS or AESA radars.
Lets not get into a discussion about whether US aircraft are better or russian aircraft are better. Thats not worth it.
US learns to take out Chinese Sukhois via Indian Sukhois (thought the Indian ones use Western/Indian avionics and have thrust-vectoring), India learns to take out Pakistani F16s, via US F16s (though US planes have unmatched avionics, far superior to what Pakistan has or can ever have).
End analysis: Win-Win for the US and India. Brings both closer together.
