I think it is actually a reasonable thing to compare. I've had similar thoughts on the Android comparison. Yes, Linux is the most widely used kernel in the world, but that doesn't mean that desktop GNU/Linux is up to the same level of usability. That doesn't mean that desktop GNU/Linux would provide a good touchscreen experience on a tablet. It could, but the entire userspace software stack is completely different. I think what it does indicate is that the kernel is featureful, stable, extensible, reliable, and a good base to build products and services from. SteamOS on the Steam Deck is a close cousin of desktop GNU/Linux, purpose built for gaming. It might be a handheld, but it's also a PC. I think the popularity of the device tells us that the compatibility of Linux with Windows software, games especially, is good enough for the average person. It tells us that people are willing to tolerate a bit of a learning curve and some differences to what they're accustomed to so long as the value is there, and 95% of things just work. It's also worth noting that many Steam Deck users choose to continue using SteamOS, based on Linux, to run their Windows games, in spite of the fact that their device will also run Windows.
