I think most of the "who would win?" debates are bolleaux anyway, as it also would depend on the quality of the training the pilot has received, and their currency in maintaining their skills gained from that training.
The Sea Harrier is the perfect example. When looking at it, "air superiority fighter" isn't the first thing that comes to mind. Although it proved that it was capable of doing that job, in the Falklands, probably because those who were in the seats are the among the best of the very best pilots in the world so were able to utilise the aircraft's capabilities.
The F-15 has the best air-to-air kill record of any combat aircraft ever made, but the pilots that made that possible are also part of that elite group. Perhaps it would have been a lot different if they were, for example... Iraqi pilots, and the Americans had the MiGs in Desert Storm?
If the pilot isn't up to it then surely it's only going to end one way?
