The M2 MacBook Air has a heatsink, it just doesn't have a fan. I bought the M1 MBA and now a M2 MBA. I would never consider buying the boxy 14" or too large 16" MacBook Pro. So to me, the M2 MBA is better than the M1 Pro/Max MacBook Pro.Ehh. The M2 Macbook Air is really good, but is it Apple's best they ever made? No, that would be the 2015 15 inch Macbook Pro and 14/16 inch Macbook Pros hands down. The 2015 15 inch has legacy as so many pros still use it, and from a technical spec the 14/16 inch are better. Especially at the spec you ordered your Air, you'd get more performance out of a 14 inch Macbook Pro instead just for the simple fast that laptop has a heatsink, as well as a 1440p 120hz display
I never owned a 15" MacBook Pro so I can't comment on that design specifically but I don't think I would ever buy a notebook larger than 13" so again, I would go with the M2 MBA.
