The Snapdragon 888 chipset provides a noticeable advantage in everyday use and demanding tasks, making the phone feel more responsive and future-proof. The 120Hz display with higher brightness is also a significant upgrade for me, as I consume a lot of media and appreciate the smoother visual experience, especially under sunlight.

Although I would miss the OIS for video, I think the better wide angle camera and 8k video offered by the OnePlus 9 would be more useful for my specific use case.
