While this is true for the benchmarks, the UX experience may not be the same between an 8GB and a 16GB depending on your use case.
My use case:
Mail, Calendar, Messages, Signal, Safari running at all times. Safari running an adblocker and with 1-3 tabs open. Firefox open as needed, adblocker, no more than one tab. Lightroom as desired.
8GB MacBook Air: slowdowns when typing. Slowdowns when switching apps. Returned.
16 GB MacBook Air: zero slowdowns, snappier than my old i9 MacBook Pro 16.
Could I have adjusted how I used my Mac and gotten a better UX? Probably, but I have been working that way for 5+ years.
