F-16 is a single engine multi role aircraft...while the SU-30 MKI is a twin engine strategic aircraft. Not sure, why you would compare the two. IF you want to compare the MKI, you should compare it with the Eagle F15s or the the F-22 Raptors.
F-16s are small light weight agile and aircarfts, they are in a different category altheogher..its one of the most successful aircrafts in the world. Its even more successful tha the F-15 Eagles
