Google likes their Pixel cameras. They also think they hold up pretty well against other phones, and they're not necessarily wrong. That's the basis of their latest ad, which pits the Pixel 3 against the iPhone XS camera in low-light situations, and the results are astoundingly clear.
Above you'll see the clearly labeled iPhone X (even though it's shot on an iPhone XS) on the left side, and the Pixel 3 on the right side. The Pixel was using its Night Sight mode to take a much brighter photo in what's clearly a very dark scene, which the iPhone XS almost totally fails to do so. You can make arguments either way about the iPhone being more accurate and less blown out, but there's no doubt that the average user is going to prefer the Pixel's shot by a majority.

That dude still looks pissed regardless of how much post you do
It is called post processing and it has nothing to do with the camera. Results are well balanced and sharp though.
BTW, Apple Store and Play Store has plenty of cheap Apps that do that too.
