I appreciate the attention to all of this. I'll just say the reason I like GW is that it just works for me, and as for your emuNAND statement I would have to disagree as I like keeping my sysNAND as pristine as possible (minus the hacks to get into GW). I see a benefit that if something happens to my emuNAND I just wipe and start over, sysNAND you could say is the same, but things happen. SD cards can fizzle out during an operation or restore, the NAND has only so many writes available (it's a lot I know, but still a limitation), your last backup wasn't taken correctly or becomes corrupt during a transfer, the verification stage reported falsely. Those are pretty extreme examples, but I've worked in the tech space long enough to know to avoid those situations at a personal and professional level.
I've kept up on the latest happenings and it really is about the time sink to get everything set up, and that every few months to a year there seems to be some new "ultimate/superior" method to hacking the 3DS. First it was GW, then ninjhax, then CFW's galore, then the golden child Luma, then A9LH with Luma, now B9S with whatever else it brings. Some people can wake up and say "eh I'll re-hack my 3DS today" and do it no problem while not all of us have that time available to do it on a whim. I have GW and it works for me, I don't even use cheats which seems like the one-upper to the product anymore.
If the GW team truly is done or they don't post any updates in the next year then it will definitely be time to switch solutions, but until then the rest of the GW users like me are just stuck in limbo.
