the T-50 are the Su57 prototypes most plane first flights are in fact their prototypes, so no it flew in 2010 unless your telling me the T-50 isnt the Su57 prototype
hell even if you want to be pedantic and take the entery date on unit production the F-15EX is still better with again 9 units in a year vs 4-6
it has cheek radars (and possibly even a radar inside the tail) to guide missiles while notching or even going cold (great advantage) while f22/35 only have the good old 60± azimuth
I wonder if the Badger will stay 9.0 or drop even more, with the terrible fire rate, awful mag size and the insane overheating that causes a jam that lasts around 12 seconds I honestly think it could go down and still have APFSDS
