The F-22 was a "money is no object" design intended to push the state-of-the-art in terms of absolute performance even with diminishing ROI. The F-35 was designed to be a mass produced aircraft that (1) could be exported widely without risk of leaking too many secrets and (2) reduced absolute performance and features based on a more pragmatic cost-benefit analysis where it only needed to be good enough and not the best possible. Economies of scale factored greatly into its design.
