Can Atmosphere run an Emunand? Load/install games from USB drives, is update-able from within itself, Use XCI games so there's no need to install them?
SXOS costs a small amount of money - but with the extra things it gives you, compared to other CFW - it's well worth money to buy it. Install it once, no need to mess about, and get regular updates and features. You can also use Atmosphere at the same time, and have the best of both worlds. However don't go online with CFW. So even though Atmosphere supports 6.2.0 - you can't play online with that. It's only useful for idiots that updated their OFW to 6.2.0 and have no other way to run CFW.
Best bet is to use SX OS - First make an emunand in 6.1.0 (exfat), and if you really need to play only - update you sys nand and use that for online, and use emunand offline for nsp installs and xci loading.
