Generally this is a correct argument - to compare hardware one needs to use the same OS/software stack. But the argument works the other way around also, if there is no identical software stack possible does it really matter how raw hardware compares? The end user running a game or an application would experience hardware+OS rather than just hardware.

Apple Silicon hardware can run Linux (with unofficial GPU support as of late, although still lacking support for the NPU), and official support for Linux on Snapdragon laptop platforms is supposedly in the works. So we should be able to do a proper comparison as soon as official support is added for both platforms as part of a single mainline kernel release.
