Well, the MiG-29 is a much better airplane than the F-16 - but that doesn't really matter when you have a radar cross-section of that looks like a giant flying mirror. The AIM-120C, launched from an F-16, has claimed two very proficient Serbian pilots and their MiG-29s.
Same thing with the EuroFighter. It might be a "better" air defense aircraft, but it was built as a gun fighter or boresight fighter. Its agility in the furball isn't really going to matter when it looks like a "shoot me" sign to a Sidewinder or Slammer. That's the big thing about stealth - not only is it hard for the enemy to find you in the first place, it's very hard for his self-guided munitions to track you.
Well an Indian Mig-29 locked on to 2 aging Pakistani F-16s with his AA-12s in 1999 & chased them off.The pilot even got a medal for it.IOW,we still have to see an equal vs equal conflict within 2 such aircraft.The countries operating their Eurofighters will be more upto date on their aircraft than the Serbs were ever with their Mig-29s
One would have to be naive to think that the AESA radar & IRSTS planned for the Ef-2000 weren't designed from the outset with aircraft like the F-35 in mind.The F/A-22 is in a different league,though.
That was actually true prior to the current generation of video-based targeting in air-to-air and ground-to-air missiles.
Hard to hide from a computer processing your multi-spectrum video image, though.
Likewise, if all of your airfields are being overflown by UCAV's that can stay over the target for 36 hours at a time, landings and take-offs become a bit problematic regardless of your airframe.
