Wow... shock... a 6 TFLOPS system with higher bandwidth can outperform via brute force an older, by a year, and cheaper 4.2 TFLOPS system? Stop the presses

.
The Pro is Polaris with some Vega features and its layout and CU count chosen to match PS4's GPU to make perfect BC super easy... X is a customised Southern Island core with admittedly cool enhancement and with the mandate to the the fastest system no matter what because they HAD to win the performance crown.
CPU choice, given the compatibility constraints imposed by the base systems which admittedly as an issue for Sony more than MS as there were quite a bit more PS4's out there and PS4 targeted software than Xbox One consoles (and Sony still cares about console generations, thank God

), seems to be appropriate for both consoles. X has to pay a bit higher OS tax as both CPU and GPU are running behind a virtualisation later, so yes it is still a bit faster but not incredibly so.
Funny that you are projecting lack of context issues and just taking about lazy devs and ignoring any historical and business perspective around the two consoles and what their purpose on the market was when they were designed... but yeah, lazy engineers...
