It's not the framerate itself that bothers me, it's when the framerate drops on demanding scenes. I'd rather have a consistent 30fps than a game constantly fluctuating between 30-60. But even a consistent 30fps is kinda a dream for the Switch, there's plenty of titles where it regularly dips down to 10fps.

Plus the other benefit to faster hardware is decreased loading times. The Switch has a lot of very long loading screens (and elaborate animations/cutscenes to mask background loading) and the PS5 with near instant loading very much increases the fun, because more time is spent playing vs waiting on a loading screen.
