Raspbian is a Linux variant, so listing it next to "Linux" may be a bit confusing. Maybe "Raspbian Linux" and "other Linux" would've been better. Or "Linux for ARM (e.g. Raspbian)" and "Linux for x86/x64", since the cpu architecture may be more important for debugging purposes than the Linux variant.
Anyway, I'm using AM on Linux, specifically Kubuntu 14.04 + 18.04 and Raspbian-based Retropie 4.4.
