Unexpected. The Lockheed YF-23[1] looks like it would fall apart if you breathed on it wrong, while the Northrop YF-23 is such a slick design it looks like it's moving while standing still.

Maneuverability in a stealth plane is not of much use. Just like the F-35, the goal of the YF-23 was to use its vastly superior stealth capabilities take out the enemies before a dogfight happened. Given that drones can take G's that will turn a human's brain to mush, this is a much more sensible strategy in modern combat and renders the F-22 vectored thrusters as mostly an expensive and useless feature that sacrifices the much more important stealth of the YF-23's hidden engines.
I believe the claims of being worried about timetables were just making up excuses to choose a worse plane. The F-22 was 100% redesigned anyway (making a "competition" nothing but a formality). It was delivered years late and WAY over budget.
