While it's true you should consider a new CFW for your daily driver,
you can have both. Any posts telling you to ditch SXOS is because they jaded and are not aware how great and convenient USB loading is, What you're looking for is EmuNAND. I wrote a guide to having 2 on the same SD. You can even shrink them. People telling you to abandon SX are missing the point
EmuNANDs (aka EmuMMC) are a copy of the internal chip. While using a EmuNAND your internal chip is not used and the system thinks the SD is the internal chip. You can have separate firmware. Standard method is 1 EmuNAND on a SD in a hidden partition. There are file based EmuNANDS but they are well know to corrupt. Hidden partitons do not corrupt. You could have different FW on them. You could just set up a seperate SD for SXOS. Beware, the sd slot is garbage and tends to break.
My
tutorial runs through how to have 2 Hidden Partition EmuNANDS on the same card. You can shrink the SXOS one if you like. I consider SXOS for loading XCI OFF OF USB DRIVES ONLY. For everything else you can use Atmosphere. Only about 10 games don't work as a XCI on USB at the moment so it is still a great solution for easy to use hot swappable storage.
XCI can be installed in the same manner as NSP in atmosphere but you will lose USB loading if you move to a strictly Atmosphere setup.
I am willing to help you if you want. PM me. We will post the resolution here to help future tempers but there is too many SXOS haters.
Even when SXOS was new and being updated they still tried to get you to switch like poorly programmed robots. They do this with lies and half truths. Like you see above. It's really sad. It's like the SXOS team stole their GF, spanked them and took away their birthday.
YOU CAN HAVE BOTH!
The choice is yours.
