Your 435 < 800 argument is only valid if ALL other factors are already equal OR the number of Pokemon is the ONLY factor of relevance. And since neither are the case, you have no argument.
If you're going call out others for fallacies, don't make one yourself.
That's not an argument, it's one of many facts that supports my argument, that people aren't just pretending Sw/Sh lacks content, it in fact does. It's the single biggest fact given it's the namesake and affects pretty much every single facet of the game, and the person I quoted specifically brought up the number of Pokemon. Very disingenuous of you to insinuate that's the only reason when my initial post made clear it wasn't.
You however claim all other factors aren't equal (this is true, but not in Sw/Sh's favor), yet provide zero explanation. Still I could have elaborated a bit more on those other reasons so I'll do that now. No mega evolutions, cut moves, story is uber minimal, route design is uber linear, no dungeon like areas, nonexistent postgame, only singles n doubles at battle tower, no triple or rotation battles whatsoever, no GTS, etc. Sw/Sh only adds Dynamaxing, Wild Area, raid battles, and camping. Also I just wanna stress again that the amount of possibilitys and options for most all of the content in Pokemon is majorly dependent on the number of Pokemon. Ex: Both Pokemon X/Y and Sw/Sh have double battles of course, but overall you can do more with the double battles in X/Y even if Sw/Sh has things only it's doubles can do.
