I'll start by saying that I have none of these phones, but I've been following them fairly closely.
I would not get a Turbo 2. Way, way too many people are having issues with charging. See
https://forums.lenovo.com/t5/DROID-TURBO-2-by-Motorola/Turbo-2-won-t-charge/td-p/3261260 (it's a very long thread, and the problem does not seem to be getting better with time.) Yes, I know that not everybody is having that problem, but there are a lot of people who are, and some people are having it on warranty replacement phones as well.
If I were to recommend a Droid phone to somebody, it would be the Moto Z Force Droid. It's a newer phone, has the Nougat update, has a better camera than the Turbo 2, and nobody seems to be reporting those charging issues.
Personally, I would still get the Pixel. Pixel count is just one specification of a camera. The Pixel camera has been rated higher by most reviewers, especially over the month than one year-old Turbo 2. (Well, of course, I would get the Pixel because I hate big phones like the Turbo 2 and Pixel XL, but, if you prefer that size, I'd go for either the Pixel XL or the Z Force.)
I don't know what your budget is, of course... if that's an issue, perhaps it's a different recommendation.
