The MBP running Linux in a VM will probably give you the T480 experience - it will be relatively slow (but still fast enough) and use a lot more battery.
I can tell you now that 2022 was the year of Linux on the desktop with Apple+Parallels! :)
I have a mini datacenter on my desk right now with 5 Debian machines running, 1 Windows 10, 1 OpenBSD machine as gateway for the others. No lag.
Just now I fired up YouTube on 3 of these Debian machines in Firefox as well as one in the Windows 10 VM. All running full screen 1080p videos (a wide second display with 3 VM's, the main display showing the Windows VM). No lag.
Also, I have _never_ heard the fan on this thing. Unsure if it has one! :)
The CPU/GPU combo is of course great, but it's the 400GB/s memory bandwidth that makes all the difference I think.
