My own experience today was pleasant. I did not follow common advice to factory reset nor wipe cache nor Dalvick cache as I was flashing a Samsung ROM. Simply entering a CWM recovery to install the Ditto ROM I entered into the upgrade cycle which kept all settings and apps. Am very pleased with updated Snote and the format of the files explorer.
It also comes with all Galaxy Note 3 features made available to Note 2 users.
I am very happy.
