Pretty much the only reason I even use Android has been the Nexus line. Why would I want vendor crapware on my phone? Why would I want a Google phone with Google crapware?
The OnePlus looks like an option, though I haven't ever used one myself. It's got an unlockable bootloader, so an AOSP variant or CyanogenMod should be reasonable simple to install.
I don't want to go back to a dumbphone. I like having a computer in my hand. But what with privacy, the unsafety of apps, the crapware … what's the point anymore?
