Defects of trial by fire in western weapons systems are just as likely as defects in trials by fire with Russian weapons systems finally facing real, heavy combat. Your examples may be valid, but similar applies to Russia as well. One example, the "top-end" Russian T-14 Armata tank, which is barely being deployed in Ukraine. Another example, Russia's newer fighter aircraft, or the Russian Kinzhal missile. But wait, there's more!

Even if the NATO Alliance weapons deployed in Ukraine don't work ideally, the total economic and technical power of the west has the ability to overcome these failures and build better for war to a much greater degree than the fragile, comparatively tiny economy of Russia can manage, and on a large scale, economic sustainability is what wins wars. Just ask the Germans after both of the World Wars they kickstarted.
