What "standards" are you comparing it to? The Switch 1 was behind home consoles, but that's not really a fair comparison. There was nothing similar on the market to appropriately compare it to, no "standard".
Five years later the Steam Deck outperformed the Switch, because of course hardware from five years later would. But the gap between the 2017 Switch and 2022 Deck is not so vast that you can definitively claim in advance to know that the 2025 Switch 2 definitely has to be worse. You don't know that and can't go claiming it as fact.
All we know so far is that the Switch 2 does beat the Deck in at least one major attribute: it has a 1080p120 screen, in contrast to the Deck's 800p60. And it is not unlikely to expect the rest of the hardware to reflect that.
The Vita had far more problems than just memory cards. You came very close to identifying what the real problem was, Sony couldn't sustain supporting two separate platforms at once. And conversely, Nintendo unifying onto a single platform was what saved the Switch.
