@DL6PL I was in the same situation with a Pixel 6a, but it was caused by an EOL USB-C port. Because of the current trade-in program (getting basically the money I bought the device for) with extra Google Store credit, I decided to go for a Pixel 10 before the Pixel 11 launch.
I was quite pleased by the simplicity of my first #GrapheneOS install.
@DL6PL I was surprised by the camera improvement, especially in low-light surroundings. That is a real improvement.
The phone feels like a premium, durable phone made to last. The fingerprint reader (I am aware of the security implications) is way more dependable than in the Pixel 6 series.
I also started to notice the brighter display.
I also found the Magsafe/Pixelsnap quite handy. (Thus I went for the 10 series.)
