I just really appreciate how quiet it runs. I basically never hear the fan, and I remember having to pin the fan in my old Macbook to max to force it to adequately cool the machine.
My personal macOS "machine" is a VM running on a supermicro threadripper pro board (along with a Linux desktop VM + random LXC/VMs). The macOS VM is significantly faster than my M1 Pro work system. I should run some benchmarks.
Some workloads are obviously faster on the big PC, but I haven't been this excited about a CPU since the Pentium 1.
