I think Switch 2 is better hardware than the Switch 1 was (relative to its time).
Tegra K1 and Tegra X1 were Nvidia's early efforts at mobile chips and both chips ran way too hot to achieve their true potential.
Since then Nvidia looks like they have learned a few things and are simply a much bigger company these days with much more resources, they a top 10 company in the world now in market cap dwarfing companies like Sony and AMD.
Nintendo's lead designers on Switch 2 also said it themselves ... they chose the Tegra X1 in 2015/16-ish because it was the best choice at the time, but they weren't entirely happy with that performance. They wanted a more powerful chip. With this chip they got to design it from the ground up specifically for the Switch 2.
I think Switch 2 will have an easier time with PS5/XBSS ports than the Switch 1 did with PS4/XB1 games. We're already seeing PS5-only games being ported without a ton of fuss and devs haven't had kits for very long, whereas on Switch 1, like when DOOM was shown on it it was a surprising moment.
The Nintendo era of them just making pure budget/weak hardware and relying on casuals to come in and fill the void which ran from approximately 2004-2012 is more or less over. This is a different era, sure Nintendo isn't in the market for a $800 bleeding edge device because that would be stupid, but they have definitely moved in a more premium hardware direction with better hardware for its time, more akin to the NES-GCN era.
