I bought the Pixel 2XL. In my limited testing, I wasn't impressed with the camera and there are no camera "pro" settings. There is no optical zoom. Low light photos are full of noise and colors are washed out. I did NOT take any outdoor photos before buying the S9+. Both are going to do a good job outside. It's the indoor shots that get tricky. I did take a (well lit) indoor selfie with my grandson with the Pixel and it turned out GREAT! The dual aperture camera on the S9+ was a feature I wanted....f1.5 offers more light in low light and less noise.
I like the expandable storage, wireless charging and headphone jack (thank you Samsung). You can add up to 400GB of micro sd storage. Fast charging is faster on the S9+ vs the Pixel. THAT SCREEN DISPLAY! I use the heart rate, stress and O2 sensors and with the S9+ you have a blood pressure monitor. Yes, it works. I've tested it several times today against my home bp cuff. Each test has been similar.
I have used an app from the Play Store to remap the Bixby button to pull up Google Assistant

The squeeze feature of the Pixel to bring up GA was the only thing I was going to miss and now I have it doing basically the same thing.
I haven't been disappointed with one of my Galaxy S phones and this one is proving to be the best yet. Did you know you can turn the Home page in landscape mode??? I've yet to try the SUPER slow mode and from what I've seen on YT, it can be tricky but I'm looking forward to trying it.
Oh, yes, buy the S9(+)
Here is an image I put together with a reading from my bp cuff and from the S9+. Results were within 3-4 minutes.
