I believe the article is heavily biased because of the following reasons:
I don't believe a consumer that has a limited budget and can only choose one of the 2 consoles would give equal consideration to budget and looks. (Come on man, 10 for the budget would suggest 2 for design, nothing more). Additionally, the design is what makes the PS5 look cool. The dual-tone, futuristic look of PS5 is way cooler than an old school cuboid.
Secondly, I don't understand what xbox has to offer to get it 15 points for its games library. You got everything on xbox, but PS5 has it better, with a night and day comparison. An 18 for PS5 is understandable, but that only means that xbox deserves a 10 at the VERY BEST.
Lastly, the reason I did not ever get any xbox was because the standards of the controller couldn't compete with the PS counterpart. Out of 10, 8 parts of user experience comes from the display/sound and the rest is played by controller, and with the experience I had with it on xbox 360 directly disqualified series X from consideration. According to me, I'd rate the controllers 9 for PS5 and 6 for series X. (I tried series X at my friend's place and yeah, I still did not like the newer controller)
