I understand why you'd ask that question, but in fact Linux audio has been quite doable for some time now and has been my *only* music OS for about 4 years. There is a significant community of Linux audio users as well. I'm running Tracktion 8 with multiple audio interfaces, USB midi connections to multiple hardware synths, using any existing VST plugins in addition to quite a few Linux-only plugins. And all with low latency. There are definitely some quirks, but once you sort it out it's rock solid. Pretty much any audio interface that's class compliant will work for low-latency recording on Linux; just gotta figure out if the HX Stomp can do it!
