The classic confusion when first installing Switch CFW: "do I install Atmosphère or DeepSea?" Short answer: DeepSea is Atmosphère + Hekate + sigpatches + popular tools, all bundled. They aren't competing — DeepSea is a curated pack that contains Atmosphère.

/bootloader/payloads//atmosphere/exefs_patches//switch/| Scenario | Atmosphère only | DeepSea |
|---|---|---|
| Monthly bugfix | Track one repo | Wait for full bundle update |
| New HOS support | Days | 1–2 weeks behind |
| Per-tool updates | Manual NRO updates | Bundle update covers all |
| AIO Switch Updater compat | Yes | Yes |
Atmosphère-only lets you skip tools you don't need:
DeepSea ships everything; you delete what you don't want. If your microSD is tight (32 GB and below), Atmosphère-only avoids the bloat.
First-time CFW install or you want everything ready → DeepSea.
10 minutes to a working homebrew environment, no decisions paralysis on which tools to grab. Many people start here, learn what they actually use, then migrate to a leaner Atmosphère-only setup later.
Experienced / want fastest HOS support / want a minimal SD → Atmosphère only.
Faster updates, only the tools you actually need.
Planning to use the secretchat.tel loader? → DeepSea's all-in-one setup is the fast lane. The loader runs under Atmosphère, but boot it on SysMMC (see SysMMC loader vs EmuMMC cheats).
