This in depth video and image comparison really surprised me. I reveal at the end which one is the Google Pixel 2 and which one is the Apple iPhone 8. They were both set to record in 4k30 (Non HEVC) for equal comparison, and their image modes were on default settings.
It is a little hard to perfectly align them as the Pixel 2 uses EIS which crops the image and prevents small movements while the iPhone 8 uses OIS allowing for more to fit in the frame when compared to the Pixel 2.
