I went the other way: from a Pixelbook to a Macbook Air. I mostly do SW development in the CLI, so the Linux subsystem on the chromebook was fine, as is macports/homebrew/etc. on the mac. I would still be using the Pixelbook if I could have replaced its battery. The low-end Air had good price-performance tradeoff, and the Neo would probably be today's choice.
I am in a similar boat. I already have Mac Mini M4 and don't do any fancy development stuff, especially not in my free time. But can't for the sake of me decide if I should go with Air M4 to match the specs, or just go full lightweight and get Neo.
