I'm not sure how the F-23 could have been riskier as it relied on much more proven technology and borrowed systems from other aircraft (including the F-15E and B-2) and the manufacturing team was Northrop and McDonnell Douglas, who by all rights, had a much better production history with military projects that Boeing (which hadn't built a new military project since the B-52) and Lockheed (who's last 4 projects had been cancelled or run fantastically over budget), so where was the "risk" really?
I understand that Northrop was having a devil of a time with the B-2 program at the time and Lockheed had recently pulled off the very successful F-117 project. That was the <perceived> management side of the risk.
On the production side, the F-23 had a very complicated titanium bulkhead which was seen as a major risk. The unresolved question was whether Northrop could really mass produce such a large, complicated part? In addition, the F-23 prototypes used very fragile/high maintenance ceramic tiles to shield the engine heat. It was understood that something much better would have to be invented/developed on the production version.
Regardless of which aircraft was awarded the contract, the "fans" of the other aircraft would have found fault with the decision.
