On paper Series X looks like a beast and definitely has the advantage over PS5, but look at XB1X vs Pro right now. X is way more powerful than a Pro, yet PS4 is hugely outselling it. Some games on X run at native 4K while the PS4 Pro uses reconstruction more, and most people don't notice or care. In fact, the increase in resolution on X has often resulted in worse performance on X titles. As I've said before, I always get both consoles and this coming gen will be no different, but judging what your experience will be on raw numbers alone might not work.
