Pixel 10 Pro vs Oppo Find X9 Pro? (upgrade from Pixel 7a)

I've had a Pixel 7a for the past two and a half years and for the most part it's been fine, but recently I've been relying on it more for taking photos and I feel like I need something with a better camera.

Since I've been happy with Google I was thinking of upgrading to a Pixel 10 Pro, but after looking around I'm swayed by the Oppo Find X9 Pro. The Oppo seems to be very highly rated with a decent camera and good battery life, but so far as I can tell only a 3x optical zoom as opposed to the Pixel's 5x zoom.

Cost wise there doesn't seem to be much in it, I'm looking at around £900 either way factoring in the trade in cost of my current phone.

I need to do a bit more research but I'd appreciate any thoughts or suggestions. Thanks!
