OK, I see that advice would have me looking at MacBook Pro introduced in 2021 or later, plus MacBook Pro (13-inch, M1, 2020). Thank you.You would be much better off upgrading to a newer Apple Silicon model than going from one 2015 machine to another.
I would but a new air. A lot faster than your current machine.
Also a new machine will last long again. A 2nd bend machine might fail in a week leaving you with nothing but regret.
