Quantity matters. This war has proven the Europe and the US (either separately or together) has a lot of advanced tech -but in a real war we would by way behind because we can’t make it fast enough. Newer might be better, but realistically the issues with the patriot is lack of quantity and high prices, not lack of advancement and for the most part that isn’t expected to change fast. What war in the near future needs is the ability to shoot down lots of cheap drones.
