Should I buy a used M2 or M3 MacBook Air?
The M3 is a modest speed bump and can run two external displays with the lid closed. That is not worth a large premium over a clean M2. Prefer whichever listing has 16GB. When an M4 is close in price, skip both.

A modest step over the M1. You notice it more in exports than in Safari.
