I witnessed my girlfriend's Nexus 6p support experience with Google and it was not pretty. I would never buy a Google phone after that. The phone, just barely out of warranty, goes into a bootloop and becomes a paperweight. Google helpfully shrugs the problem off on Huawei, and Huawei will of course not support the product since it's out of warranty. There is no repair option. I tried Android early on, had similarly…
On the contrary, because I bought the Nexus 6P from the Google Store, they replaced it with a Pixel XL for free. The Google experience is terrible through a third party, but their Google 'direct' experience is pretty darn fantastic.
The replacement they sent has the wide-spread microphone issue out of the box, and I just haven't had the gumption to deal with yet another support experience.
I've had great luck so far with my Pixel XL and love it - one of the best phones I've ever owned. But the Pixel I bought along with it has been by far the most unreliable piece of hardware I've bought in a decade. It's really soured my opinion of Google, even though so far they have (grudgingly) replaced the item.
I'm dreading replacing it for the third time, as I know they will refer to their 2 replacements limit in their warranty contract. Zero of those replacements were anything but known hardware issues on the handset itself thousands of others have reported on-line.
