the N6 and the turbo 2 have almost the same specs, I think the only exception is the finger print scanner
They're very similar or the same in a lot of specs, but there's a handful of differences in the devices and in things I have to consider in my purchase:
Turbo 2 Pros:
+ Wireless charging (I have 2 Qi chargers already, including a nice stand charger on my desk at work - it's really nice to be able to see/use the phone without picking it up, and not have to unplug anything if I do pick it up, and be able to keep the charge topped off with no effort)
+ Shatterproof screen
+ A bit smaller overall size
+ Slightly bigger battery (though it's unclear how real-life battery life will compare)
+ A bit cheaper after $200 trade-in
+ Can do interest-free financing over 24 months via Verizon
Turbo 2 Cons:
- No fingerprint scanner (this is kinda big for me, as I run a business and security is important to me. Without this I don't really lock my phone, and keep my password manager behind a PIN number. A fingerprint scanner would up my security and peace of mind quite a bit)
- Likely to get fewer updates, and slower
- Smaller screen
Nexus 6P Pros:
+ Fingerprint scanner
+ Larger screen
+ More/faster updates, longer overall support
+ Cheaper (without trade-in)
Nexus 6P Cons:
- No interest-free financing
- Have to wait longer to get it
- Likely a more fragile device (though I am very careful with my devices, and the only smartphone I've broken/ruined was one that got left in a kayak underwater for a week... long story, RIP Droid Razr.)
- Bigger overall size
- No wireless charging
- Less proven manufacturer (Huawei) vs Motorola/Lenovo
Other points - both seem to have good cameras, and I'm not super picky about my cameras (if I want good photos, I have a DSLR), so I consider the cameras close enough to be a draw. The TypeC connector is a better design and the future, but all my cables are microUSB, so I consider the pros/cons of that a draw. Both have same processor/RAM, both have always listening, etc.
Honestly, it mostly comes down to the fingerprint scanner, financing, and availability that has me wrestling.
