A lot depends on your budget of course, but if you are looking for productivity use then the Note 4 is my choice for the high-end. The stylus on the Note series is actually really useful, and for that reason, I would pick the Note 4 over the LG G3, even though I personally bought the LG G3. But my primary uses were going to be gaming and watching movies, so I didn't want the stylus. That's just my personal opinion, but our review of the Note 4 should also help you choose.
