Go read for yourself if you're so interested, and see if it was "some person", or the primary point being pushed in the thread. You can start with this post;
The xbox twitter fanboys are pushing that SFS 'streaming speed advantage' harder than ever. I'm not very tech savvy but this doesn't make any sense. If SFS actually gave Series X the upperhand in I/O-speeds (am I understanding their point right here?), how on god's green earth hasn't this...

That's not to mention the leaked Spiderman loading time constantly being compared to a non-optimized State of Decay backwards compatibility title on the Xbox Series X that came back again and again in that thread, despite that faulty argument being addressed multiple times. I would look them up, but I have better things to do with my time.
People without knowledge have opinions, and inevitably some of them are too loud.
The main reason that the PS5 SSD was hyped to the moon was because it was the only specification advantage it had on paper, and we all know it. With that came the inevitable downplaying of the XSX as much as possible, beyond all reason. People are still looking for this, which is what the whole loading time comparison is all about. Some are still desperate to find the loading advantage on the PS5.
Don't get me wrong. I have no problem with the comparisons. It's fun to think about, and some people that love tech might like those details for the sake of it. But for all practical purposes, those comparisons are futile. Add in Quick Resume, and the whole game shifts again.
Because truly, honestly, objectively, if a game loads in 6 seconds rather than 7, nobody is going to notice or care. You buy a console to play games, not to do side by side comparisons. And if someone really buys a console based on that second of difference, they need to get their priorities straight. But priorities haven't been straight ever since the spec announcement of these consoles.
