I would just go ahead and update now. It only takes about 5-10 minutes and its easy as pie.first time i read about b9s, what boot times are faster? the first time you boot up your 3ds?
or would games boot faster.
i have both my og and n3ds on a9lh with updated sysNAND luma cfw.
is it better to update to this new b9s now or worth waiting, considering some saying it is not so major for end users but more for devs.
More stuff will come out in the future but updating it now can save some headache in the future. Plus you can brag to others pronto.
