The Note is like a fully loaded Lexus, it's got everything, all the bells and whistles, but can have some weird issues and might not be the best over the long haul. The pixel is like a Civic, always reliable, great fuel mileage, but no options, but it will run forever.
I have spent very little time with the pixel, and it is a very nice phone, fast, clean, excellent camera, and will do everything you want for a long period of time.
The note has AC and cruise control. It's one handed mode blows the pixel out of the water, as does it's picture in picture. Its those options as to why I prefer samsung.
Many of the samsung apps are better, the browser is far better, email is better as it the text app, and they can take theming and you can change the background on the message app, and have scheduled messages. It's calendar app is just as good and can change the background. However, google has many good apps as well. All those I mentioned are also just as good, and many find better. The samsung messages app doesn't have as good GIF support and Gmessages has web support. If you use Bixby the samsung apps integrate excellently and better than GA, google assistant uses everything well but not as good as samsung integrating with itself.
As for the screen, who cares. the pixel has it's issues and the note is a lot better, but unless you are doing something special, who cares.
Another issue. The pixel doesn't have a headphone jack, micro usb, wireless charging, pro mode on the camera. But the pixel has far better and longer security update and probably better customer service.
