Upgraded galaxy tab s last night and not seeing a huge difference. Typical changes to interface here and there that you always get with an upgrade, generally looks cleaner and sharper, seems to be running faster however I also cleared the app cache just before the upgrade so could be that.
I like the pop-ups which mean you don't have to unlock to see what is in notifications but then that's been in iOS for donkey's years, never understood why Android didn't have that sooner or maybe it did and i just missed it.
Netflix finally works 5 months after buying the device, was a bug in Samsung Netflix version that prevented login, very annoying and glad it is fixed.
