While the Raptor has evolved into the single most capable air superiority fighter ever built, the YF-23 design—especially when combined with General Electric’s YF-120 variable cycle engines —was arguably more advanced. Compared to the YF-22, the YF-23 was faster and stealthier, but many have argued that it was less maneuverable than the thrust vector controlled precursor to the Raptor. However, the difference in maneuverability between the two designs was far slimmer than many might have imagined.

“Interestingly the YF-22 and YF-23 had exactly the same trimmed AoA [angle of attack] of 60° [degrees],” Paul Metz, who was Northrop’s test pilot for the first YF-23 prototype and who later became Lockheed Martin’s chief test pilot for the F-22, told me in an email in 2015. “The YF-23 could do it without thrust vectoring. Those V-tails are very powerful especially when coupled to an unstable airframe.”

But is still 10,000 lbs heavier
disconnectedradical wrote:F-23 is actually longer than YF-23 and looking at cross sections the fuselage volume increased especially at middle.

Hence will be much heavier.

the YF-22 prototype beat the YF-23 and post above clearly says why. I'm not saying its undefeatable but it is better than than anything in service in A-A and better than a fictional F-23 variant.

F-22 and YF-22 material wise are similar, F-23 and YF-23 aren't. F-23 would be plastic plane (over 50% of plane weight would be composites). YF-23 was metal plane. So we can't use F-22 and YF-22 analogy.

YF-22 was more agile that is sure but YF-23 had much better supersonic range, this was confirmed by Northrop ATF folks, YF-23 could do whole sortie flying supersonic and F-23 would be even better because it would carry more fuel then YF-23.
