Can middle weight fighters compete well in today's market?

middle weight fighters (in the export market) as in the Rafale, Eurofighter, and F-18E/F Super Hornet.

it would appear that many customers prefer light weights (such as the M2K and Gripen) or heavy weights (like the F-15 and Flankers)..

the dissonance in capabilities between the Gripen and especially with the Typhoon and the Rafale does not seem to be that far, especially since the Gripen appears to be integrating the Meteor first and currently has better A2G capabilities..thus it is lacking more in range and payload.. although it makes it up with cheaper operating costs and unit costs which will appeal to many..

while the F-15 and the Sukhoi by far, have much greater carrying capabilities and range, while having alot of room for upgrades (and with the latter, has a cheaper unit cost than the 3 middle weights)..
