Alright. I tried to stay quiet on this but here we go:
- Atmosphere: The developers of this custom firmware have done an absolutely amazing job. They laid the groundwork for everything else that has been released so far, Atmosphere is the only reason ReiNX, and SX OS exist and work as well as they do. I will never understand why people complain about it not being released. It's out there. It's on GitHub. There you go. There's just no "plug and play" solution for it yet, but there will be soon, even though it won't have many benefits for the end user who isn't interested in developing anything. They're also working on emuNAND and other important features, which other devs will then implement into their solutions as well. Don't expect anything like emuNAND from ReiNX or SX OS as long as it hasn't been implemented in Atmosphere.
- RajNX: I can't say anything about that one. Never tried it out. Seems to be a rip off of ReiNX.
- ReiNX: This is what I'm using right now. Yes, there is some confusion about the different versions of SDFiles, yes, it's a little bit annoying that there doesn't seem to be a definitive installation guide for it yet. However, even given all these "problems", you should be able to get everything up and running in a matter of 15-30 minutes. Once everything's working, you don't really have to bother with keeping the SDFiles package up to date. Everything is working pretty well right now. I've set up my CFW a couple of weeks ago and haven't had to change anything ever since. Everything just works. Yes, the community is weird. Mostly because it's full of teenagers who just want their free games. It's also full of people feeling like they're scene insiders because they've joined a Discord server. Leave them be, don't engage, and you'll have a good time.
- SX OS: I've used a SX Pro ever since it was first released and had absolutely zero problems with it. The only reason I've switched over was because I simply wanted to mess around with something. It's a shame that every one of their release threads gets clogged up with 50 pages of bickering with the same arguments and counterarguments. I really don't believe they're giving anything to the scene or bringing it forward in any way, but eh, I saw it as a milestone in the early scene days and wanted to give it a shot.
Also, by your definition, what is a "real CFW"? Luma certainly isn't. Luma is an assortment of patches applied to the original firmware. That's all. Don't get me wrong, I use Luma pretty much daily and I love it, but it is not the holy grail of custom firmwares.
Conclusion:
If you want to run unsigned code on a Nintendo Switch, there are a couple of reasonably easy solutions right out there for you. No, there isn't a "community standard" like Luma at the moment. Seeing as most people are only here for pirated games, and the Atmosphere devs are against that, I don't believe there will be a standard in the very near future. No, none of the free solutions are currently being spoonfed to you, you will have to do some reading and research. In my opinion, this is what console hacking scenes should be like though. People should have to inform themselves and have legitimate interest in the scene, and not just want a quick and easy way to play their warez. Don't get me wrong, I'm not opposed to a general beginner's guide, like we've got on the 3DS, that guide is pretty much perfect. If you truly want a plug and play solution that offers little to no work from yourself, invest in SX. You won't get anything too fancy, but at least you'll get your warez, GPL violations included.
However, nobody with any sort of reasonable thought process, can deny that Atmosphere is laying the groundwork for everything the Switch hacking community has at the moment. I'm sure that once a 1.0 release with emuNAND and maybe even something Rosalina-esque is released, the scene will gain a lot of additional momentum. I'm certain that there will be a version with sig patches in a matter of hours or days, maybe Atmosphere won't even do anything against you loading a sig patch kip alongside it, I don't know.
All I can really say is: Give it time, don't complain if you're not going to actually add something to the scene yourself-
