Nothing(TM) looks like it could be a decent choice, but they're generally weak hardware compared to a 9 Pro XL class device, and I'm not a fan of Samsung any more as a company, though it seems a S2X Ultra might be the only real option.

Even the Nothing Phone (4a) Pro is getting close to the price of an S26 here and the S26 will absolutely blow it out of the water when it comes to pretty much every facet of the hardware.

Pixel 9/10 Pro XL is a midrange SoC sold at flagship prices. Even the A57, which is a midrange Samsung model that will soon hit 350 Euro is faster single core than the Pixel 9 Pro and on par multi-core. Also has better battery life and despite only being 0.1" smaller weighs 42g less and is much thinner. Gets supported for 6 years and also gets monthly updates. Also doesn't die frequently with spicy pillows, camera bars that drop off, etc.

I still buy Pixels because it has an unlockable bootloader and can run GrapheneOS, but Google's pricing is insane and I wish that they would go back to the old price points. The 10a is the only Pixel with somewhat reasonable pricing for what it provides, but unfortunately they made the hardware differences larger than in the past (e.g. be not upgrading to the latest Tensor SoC).
