I am not missing my note 5 at all since I gave it to my wife to use.
This phone is awesome. Both screens are really great, the camera is better, and hook it up with a good set of ear buds or cans and nothing else comes close.
Battery life is not as good as as the note but we don't have a package disabler for it but I can make it completely through the day without charging.
I've always put some type of case on my phone, with the exception of my s6 Active that I gave my son in July and now the v10. On my note 5, I was sweating bullets each and every time I had to use it naked.
Now the spen is really cool, and if you use it everyday there's nothing better, but I didn't really need it for day to day usage.
Now the only gripe I have is the external speaker isn't loud enough, but I manage to get by with out missing calls or text with it.
The note is a good phone, once you have it set up right, but head to head in real world usage the v10 is a better device. It can take more drops and bumps, it sounds better listening to music and video when used with buds or cans, it takes better pictures and you don't have to worry about storage or battery degradation with it.
A couple other things .. I wear mine in a holster for work and had my note shut down by hitting the power button all the time, that doesn't happen with the v10.
I don't have to turn the phone on to see the time with the second screen.. That is a blessing since I don't wear a watch. If I do turn it on it's by double tapping it on and off which once you get used to you won't be satisfied using the power button anymore.
I've had many of the note series and they are excellent phones, but LG surpassed them with this phone IMHO not only because of the SD card and the removable battery, but because of the build quality of the v10 internally and externally.
That doesn't make the note 5 a loser but makes the v10 a winner and moves it into the elite group of phones to buy.
If you are worried about buying one, because it isn't a Samsung, don't. I have compared both side by side and don't regret my decision on getting mine. It does more for my day to day usage than the note could ever do.
