If aircraft are supposed to stand still vertically while fighting, then the SU-27 wins hands down.

The SU-27 would be a somewhat equal match for the current versions of the F-15, but again the training and capabilities of the pilots involved (not taking into account the input from Command and Control) would be the determining factors.

But again, I'm still pointing out relevance to 20th Century tech and capabilities, not current.
