northrop f20 tigershark

i want an educated talk on the f20 and if it had been made instead of the f16, also how would the f20 compare with the usual flanker, fulcrum, j10, eurofighter, grypen, etc. what we compare the f16 to now. how good is the f20, in the 80s, 90s and now? i want to hear proper debates and pros and cons, eg which can turn better or fight better? so over to you…

ps the f20 is my fave jet but on planes im unbiased…:D
