I love the camera on the S7e...but my experiences with the Pixel XL and S7e are different than yours. The pixel shoots great accurate photos no matter what and with no post editing on my part. The S7e photos are great but tend to be a little over saturated. It makes the colors really pop...but not accurate imho. Sometimes the color blurs because they are over saturated.I might be the only one that thought the Pixel's camera didn't live up to the hype. When you got a shot right, it was gorgeous, but photos would too often come out a little blurry. It forced me to take multiple shots to ensure I got it right.
The S7E... no fear. Even if I can only get one shot in, I felt confident it would be great. I really couldn't say the same with my Pixel camera experience.
