For everyday use, I would choose between these based on camera philosophy and software preference. Pixel is attractive if you want a Google-first interface and a camera that emphasizes simple point-and-shoot results. Galaxy is attractive if you prefer more features, customization and Samsung’s broader ecosystem.
Battery comparisons should be based on mixed mobile-data use, not just video playback. Also compare how each handles the exact camera situations you care about: people, motion, night scenes and zoom.
If you keep phones for several years, local service and accessory availability are worth considering too. Both can be sensible choices; the best one is usually the phone whose interface and camera output you prefer every day, not the one that wins the most specification rows.
