[Q] Note 4 - to update ot not to update, that is the question

Just bought an brand new Note 4 from B&H Photo after a long deliberation between the Note 4 and 5. Anyway it is the AT&T model, unlocked and running Kitkat 4.4.4.

Now the update has downloaded, and it starting to nag, I did run the script that is supposed to prevent this but no dice, anyway still needs my permission (I think) to run the update. I have started reading the 53 page long thread about what happened to your phone once you upgraded to Lollipop, sorry but I do not have that much time to read through 53 pages. I did read a few and its a mixed bag so far.

So, should I upgrade or not to 5.0.1 ? Just a simple yea or nay.
