The installation took only a few seconds to brick my system (yes, it's supposed to do that!) so that I never needed to try jamming a paperclip into my Joycon rail ever again. While I was hesitant at first, I made a full backup of my system (32+GB) and decided to bite the bullet. One of the key features is an Auto-RCM Installation that 'works on all firmwares'. If you are less technically inclined and have a few extra dollars, you could splurge for the SX Pro which comes with a 3D printed Jig and USB dongle that's (more or less) a plug and play solution for around $40. Since the SX OS by itself is around $25, anyone on a budget could make due by using a paperclip to do the 'one-time' RCM boot and a PC whenever the console is shut off or battery is completely drained. The RCM payload doesn't come with it's own injector, so you'll need to use one of the already existing ones online as well as your own Jig to boot into RCM (ReCovery Mode). Lots of file manipulation, low compatibility, and spotty save support make it a less than desirable means of swash-buckling, and if LayeredFS is a leaky paddle-boat, then consider SX OS the shiny new S.S. While the world recently came across backup loading utilizing a tool meant to help with ROM hacks and fan translations (LayeredFS), it comes with many caveats and issues. When sailing the high seas of software piracy, some vessels just aren't the same.
