Is Switch 2's 256gb on par or worse than PS5's 825 launch model?

Well, currently 3rd rated game this year on MC, Split Fiction, uses 73GB (as opposed to 85/85/79 on PC/XBOX/PS5)...physical key-card, so download all to play. So that's quite a bit for one game.
So yeah, unless you play only Nintendo physical games, plus 3rd parties that ship fully on cards, 256GB is not that much.
