Welcome to the long list of disappointed people in my life...
The UAE F-16s could be comparable to Block 72+ or V upgrade now even though they stayed ahead of all F-16 versions for nearly 2 decades. Now other 4.5 gen aircrafts are on par with block 60's capabilities. The edge holds against IriAF, yes.
One area where block 60 takes edge is over Mirage-2000 which even when upgraded will be replaced by Rafale in UAE-AF.
UAE F-16s have not seen much combat operations against a capable or comparable AF. This is where block 60 could have shown its prowess. It has long range A2G weapons (even local ones) which PAF lacks.
Sooner or later, UAE will induct a 5th gen, probably inclined towards KF-21 for now. For the right price, UAE will get rid of its F-16s at some point, its not a golden baby that needs to be held on forever. Maybe 2035+.
