I say sell. 95% of the time, if you have to ask, you won’t need it; use that cash for something else, and let someone else use your Switch.
One caveat: my sibling’s Switch 2 broke soon after buying (WiFi just died), and they had to wait a bit for an exchange. My impression is the Switch 2 has some QC issues.
So maybe keep the Switch 1 a bit, as a backup in case your 2 is a dud.





Also, one thing I hate is the disparity in consumer stuff.
WiFi 7 is already everywhere. Everything new supports it.
2.5G, though? Switches for it are expensive. Heck, our new smart TV comes with a 100mbps Ethernet port, one so bad we had to switch to WiFi because it was dropping streams.
