I'd buy an Intel mac from 2015. The modern ones all have their well-documented problems. The ARM based macs will almost certainly have a small period of instability and incompatibility when they first launch, just like the Intel macs did.
So the new MacBook keyboards seemed to have the debris issue licked, and a little more travel. That’s all I need, but if you want more travel I can see it’s not there for you yet.
