I came from the Galaxy S6. The S6 was a great phone in terms of design and performance, but the battery life was just awful for me. I disabled everything I could and restricted background data on almost everything and the only way to make it through the work day with moderate use was to keep it in battery saver.
The Note 8 is my first Note phone and I absolutely love it. I can go 2 days on a single charge with light to moderate use and the screen is amazing. I didn't think I would like the infinity display, but I was wrong. I don't use the stylus all that much right now, but I like having it because it does make certain things easier (photo editing, copying text). Also, the 6gb of ram is a nice touch. I just got my Dex station in the mail and can't wait to try it out!
