Depends on what you plan on playing. As others have pointed out the majority of third parties have opted for the 1GB key cards which will utterly destroy the Switch 2's 256GB of storage.
I personally only plan on buying Nintendo first party games on my Switch 2, and only the occasional third party game as long as it's on card (currently I'm only interested in CP2077 which is confirmed to be 100% on the card including the expansion)
Meanwhile on my PS5, I very quickly ran out of storage after installing just a handful of games despite having the games physically. Remember, it wasn't actually 825GB of available storage. It was 667GB. You lost 150GB right out of the box due to the OS.
Remains to be seen as to how much storage the Switch 2 OS will take up, but with the kind of games I plan on buying for the system, the Switch 2's 256GB of internal storage will vastly outlast the PS5's original 825GB of storage for the entirety of my Switch 2's life.
You called down the thunder, now reap the whirlwind
