I am sure they are right.
F-16 is the oldest NATO fighter in service dating back to the late 70's. SU-35 is the latest and greatest Russia fighter dating from early 10's.
35 years does matter! And it is also a 4G vs a 4.5G.
But it would be more fair to compare F-16 with MIG-29, MIG-31 and SU-27 that are only 10 years newer than F-16. And it would still be relevant as Russia actually have way more of those than of SU-35.
