If you want the free CFW that is ahead of the game, probably Atmosphere. But since your device's firmware is still at 4.1.0, you could still try all. Just do not upgrade to firmware 6.2 to make it feasible.
Personally, I use ReiNX which I also liked. I stick to this CFW since I could still play the latest games I like while on firmware 6.0.1.
But given the circumstances, Atmosphere really is leading the competition involving the 6.2 firmware, not to mention good LayeredFS support for running modded contents.
