When we talk about missiles, bombs, radars, ECM etc that are carried by a fighter aircraft.......we are in fact talking about a weapons system (the whole package)...........and we cant compare then the two aircrafts.......
This package can be broken down into Flight Performance, Radar and Avionics, Weapon Systems, Situational Awareness, Serviceability and Maintainability and perhaps some others.
Only the aircraft itself is always judged by its flight or aerodynamic performance and there are several performance aspects.
First everything in clean configuration..........landing distance, take-off distance, minimum landing speed, range (both low-level and altitude), endurance, climb rate, instantaneous and sustained turn rates (at different speeds and altitudes), high angle-of attack performance (max angle of attack), corner speed, roll rate, acceleration in vertical climb, ceiling etc
Then all these performance criteria with various loaded configurations and seeing that how fast the performance falls down. Flight Performance can be somewhat judged by the thrust-to-weight ratio and wing-loading of the aircraft.
But only the aerodynamic performance is not enough, as we saw with English Electra Lightning, which was the first aircraft capable of supercruise in early 1960s but due to advancement in Weapon Systems and Radar-Avionics, had to give way to modern fighters.
The pilot's point of view is also important like cockpit visibility or over-the-nose visibility, ease of controls (HOTAS), HUD/HMS/HMD etc.
Personally to me, Flanker is the champion in flight performance that broke the records set by F-15 Eagle, Gripen is champion in serviceability and maintainability, Eurofighter being champion in high-speed maneuverability, Raptor in stealth.....and I cant say who is champion in avionics and radar.....because these things can be improved and installed with some margin...........for weapons systems, many platforms are good in this area......
