Fair enough. I respect your opinion on it and I will read about the phone some more. I just really like the idea of pure Android. I really want a small pure Android phone that is built well. I liked the idea of the Essential phone.
Even that's changing now that google is doing their own thing with their pixel rom. There was a time where pure android had legit benefits, as in being the smoothest option, and less nonsense, but most oem roms have trimmed the fat and only left the good stuff (that google will eventually roll into stock android years later), and modern processors + butt load of ram basically bridges the gap in terms of performance.
Currently with pie, i'm just not a fan of the god awful pill, and on pixel 3 phones you don't even get the option to change to 3 buttons, while every other company is experimenting with full screen gestures to varied levels of success.
I'd recommend you wait for the pixel 4 which is rumored to have 6+gb ram, which hopefully should fix the lag issues people are talking about, especially on the camera, which is its one main selling point. Unless you are fine with Jumping to the 4 in a few months.
