[Nexus 6P Q&A, Help & Troubleshooting] Chris Hansen:
Hey there, sorry I missed your response.

For me, I had a lot of problems with my Note, which ultimately led to me selling it. Here's a quick list of what I can think of off the top of my head:

Note 4 Pros

Great screen

Good feel (the faux leather-ish material on the back, specifically)

Wireless charging (I purchased the official Samsung wireless charging back)

Quality build materials, although the pen felt a little cheap, but I never had any problems with it

SD Card

Removable battery

Cons

Awful battery life (some days it would not last more than 5 hours with about 2 hours SOT)

Poor performance (lots of freezing, overheating for no reason)

Camera problems (sometimes the Samsung camera just wouldn't open, other times it would freeze, other times, it wouldn't take a photo, etc.)

No root (at the time, anyway)

Fingerprint reader was not reliable/clumsy to use

The bolded issues were dealbreakers for me. This was my work phone as well, and there were times where my phone either died or failed to let me answer calls.

Nexus 6P Pros

Great screen as well

Stock Android/timely updates/dev previews

Rooted the day I got it!

Awesome battery life, even on N DP5, I'm getting through the day (~18+ hours) with double-digit, usually 20%+ battery left

Fast charge

Quality build materials, specifically praising the aluminum back, it is both gorgeous and functional

Fingerprint reader is fast and reliable. From my experience with the Note, I didn't expect to use it all that much, but I use it all the time for unlocking my phone.

Camera takes some really fast (and quite good) panoramas. They always seemed to take way too long on my Note, but they're a breeze on my 6P. I take quite a few of these for both personal and professional reasons.

Cons

USB C (in itself is great, but I have no other type-C devices, making all-new accessories kind of annoying, as well as now-obsolete chargers and such)

Overall, the camera wasn't as good as I hoped, though it is still great. Some suboptimally lit pics (not even low-light) come out a bit grainier than I would like, but HDR+ does a pretty good job at making them look good. There is the issue with slow-motion video recording as well, but I have literally only tried that once.

Auto-brightness on this phone will leave you scratching your head sometimes, as it usually doesn't adjust properly

The cons almost aren't even worth mentioning. I do love USB-C and can't wait for it to be adopted universally. The camera quality I am scrutinizing for sake of fairness and lack of other things to gripe about.

The only one that really makes me feel disappointed is the auto-brightness, but I just use an app to fix that.

No removable battery concerned me at first, but it's a non-issue with how long this thing holds a charge and how fast I can charge it back if needed. It's literally the first phone I've ever owned that I have been able to leave off the charger overnight and not have to worry about it being dead in the morning.

Expandable storage is also a non-issue as I picked up the 128 GB model, and I've never even come close to filling it up.

MKBHD summarized it well when he said something along the lines of:
