From this table, we can't say which one is surely the best CFW but each one has its own pros and cons. Which to choose for hacking your Nintendo Switch, according to me, depends on your budget:

• enough of budget ? buy sx os of course, around 29 dollars
• short of budget ? install Atmosphère CFW instead

How to install CFW on Nintendo Switch ?

That depends largely on the CFW you choose. I personally chose the SDFiles setup, so that I can switch easily between multiple CFWs and patches and such easily through Hekate. The way you'll want to set this up also differs depending on your platform of choice.

The first thing you'll want to do is put your Switch into RCM. You do this by using an RCM jig to put your Switch into recovery mode by tapping Vol+ and Power at the same time. Don't hold them down, just tap them quickly. 

Then, depending on your device, simply connect your Switch via that appropriate connector, load the payload you want to send with your program of choice, and send it! On Windows, you'll need to install a specific driver, which you can do right within TegraRCMGUI.

Or you have still other choices as below to inject the payload: 

All of the following currently require an RCM jig to perform.

Platform	Materials	Software
PC	USB C cable	TegraRCMGUI (Recommended)
Mac	USB C cable	Web Fusee Launcher
ChromeOS	USB C cbale	Web Fusee Launcher
Android	USB C cable, Adapter for phone USB port	Rekado
iOS	Lightning -> USB C cable, jailbroken iOS 10+ phone	NXBoot
Portable	Fusee dongle solution (brands vary, all functionally identical)	Programs may vary, depending on how payloads are sent to the device/updated

What to do if your switch hacked

First and foremost, if you care about online play, enable airplane mode! Keep offline as much as possible when using Homebrew and such, as there's always a risk of getting banned.

Now that you're up and running, you should be able to launch the Homebrew menu! Go down to the Album applet and open it up. You should see the Homebrew Menu in front of you, along with any apps you installed, if you chose to do so! Apps are added to the /switch directory on your SD card. 

If you'd like to transfer apps and stuff to it without having to take it out, you can use FTPD as a method of wireless file transfer, along with a client like Filezilla or WinSCP.

As for what Homebrew to use, there's plenty available! I won't be listing a lot of it because of time restraints and such, but there are a few good ones out there:

• Checkpoint and EdiZon, save management applications!
• RetroArch, an emulation tool with 44 cores currently supported!
• Tinfoil and ZeroTwoXCI, title managers/installers for Homebrew and legally owned backups! (Note: Going online with apps installed via anything but the eShop is a guaranteed ban)

To install games backups, you can use tinfoil too, or goldleaf homebrew. But for sx os CFW, it has its own tool SX Installer to install Switch roms xci or nsp and manage nsp files.
