There is always reason to use emuNAND over sysNAND regardless of ban. - Brick-proof. Installing your NSP's under emuNAND makes your Switch 99% brick proof. Anything happens to your emuNAND, delete recreate, start again. sysNAND? did you have a backup, hope the backup restores successfully. Hope there are no issues etc. - I will ALWAYS use emuNAND even if I ever get banned.
