In short, is the Pixel worth it? Go...
It's a fun distraction, and the camera is surprisingly good so far in my VERY unofficial side by sides, the Pixel is winning by a VERY slim margin. But truth be told if you are happy with your iPhone and you don't rock 2 phones, it's probably a pass! I do like it though. I change Android phones about every 3 months. The Pixel is replacing a One Plus Three (which replaced a Nexus 6P) You get the picture.
I bought an Honor 8 too but cancelled it, might still end up trying 1 eventually, and the Axon 7 is on my list of things to try too! (Probably get a OnePlus 4 or whatever the next OnePlus is called LOVE those phones!)
