I wouldn’t call it downplaying. Truth be told both systems are great machines. People just going by the criteria they been comparing for generations: who has the most power.
I get it that It’s in Sony’s best interests to really push the ssd aspect since that’s the one spec they have on Xbox. But apples to oranges if you look at the spec sheets side by side Series X edges it out in almost every category
Your statement are complicating each other, how can you determine the spec edging each other if you even cannot compare apples and orange LOL. You gotta choose between "you can compare " or " cannot compare ". Even on paper it cannot and it need further test and benchmark. Also even if there is a different only 15% less, and i believe all game studio want to bring their games on the same quality across the platform. They will sacrifices 15% different to bring parity for both.
