Whereas the MacBook Air is still amazing. Has a good processor now, good sized hd, no Touch Bar, Touch ID, light, great battery. Lack of ports is a thing but good thunderbolt 3 docks are about. Still the best laptop for me I’ve ever used.
My 2018 Air is great (except...keyboard). Don't rely on the review of the haters. If Apple has fixed their keyboards then you've got a chance to buy another great product IMHO.
Cooling on new Mac laptops is nearly-nonexistent. I'd wait for ARM (if that will even be usable for you) or go for a PC if you plan to do anything except editing text files and using SSH.
Did the airs ever change their keyboards to the bad style? In either case, yes the 2020. My main beef with airs before was the speed but the new ones, while not blazing, are perfectly fine for daily use. Hardly any waits foe the cpu whereas with previous airs, was a bit skimpy there. Also only talking about the best processor they’ve offered as that’s the only one I’ve bought because uhhh work was paying for it. :)
