What’s better for college: MacBook Air M4 or Mac mini?

Hey everyone, so I’m currently in my last year of high school, and going to college the following year for an aircraft maintenance and engineering program, i currently own an M1 MacBook Air, and was wondering if should get tho m4 MacBook Air, or the M4 Mac mini, what would be the most useful in that scenario. Unless I keep the current M1 and get a Mac mini, or I get only the Air, or I’d there any other machine you’d recommend? some help would be appreciated, thanks
