Purchase advice: used M1 Air or New M3 Air

I am planning to get a MacBook again after 2 years. I live in Europe just for reference to the prices I mention. So my options are, as the title states, MacBook Air M1 8/256 used with 84% battery for € 465 or M3 Air 16/256 new for € 850. I can totally afford €850 but I don't want to spend almost x2 and possibly not make much more use of the extra features and power. I am planning to do Web Development and documentation and etc and daily browsing with this to-be-chosen laptop. Thank you in advance
