So far I haven't got any problems with Note 3, so kinda no reason to update it to 4.4, but does that update do more good or harm to me, since no way to dowgrade back.
About ext. sdcard writing problem, I haven't noticed anything that differs between my JB Note 3 and KK NP 12.2
Main reason why I would want KK on my Note 3 is Samsung SideSync feature (works only on KitKat devices) that I could use my Note 3 through my NP 12.2..
But is that really that good reason to update fully working phone (if there comes some problems with KitKat)??
Please help me with this, thanks :P
For me personally, I don't see more harms compare to the good parts.
I understand so many ppl do complain about KK firmwares. And to be frank, those problems stated, I have never experienced on my N9005 device (**touch wood**)
My ext. sd card writing also has no problem eversince I upgraded from JB to KK for the first time.
S-view cover, some also stated they experience problems, but my S-view is working just fine. And I have a fake S-view (made in China) :P
But all is your decision to make. My only advise is... if you really want to upgrade, after the upgrade is done, no matter you still can go through the homescreen, try to do factory reset from stock recovery. This step is very simple, but do help a lot to avoid future unnecessary problems (example : battery drains, FC, freeze, sudden reboot, phone very slow, etc).
So, my suggestions is, do backup of your important data (before upgrade) to your external SD, or to your laptop/PC.
