[NL] Upgrade from S22 Ultra: S26 Ultra (€760) vs. Xiaomi 17 Ultra (€884) vs. Waiting for Oppo Find X9 Ultra?

Hey everyone, looking for some advice on a much-needed upgrade from my Galaxy S22 Ultra here in the Netherlands.

My priorities are Camera, Battery, and Performance (not for gaming, just general productivity/longevity). I used to be a heavy S-Pen user, specifically for the Bluetooth remote shutter/gestures, but since Samsung has removed that functionality in the new models, I’m feeling less tied to the Galaxy ecosystem.

I’ve found two solid deals, but I’m torn:

1. Samsung S26 Ultra (512GB): Managed to get a trade-in deal for €760.
2. Xiaomi 17 Ultra: Available for €884 via contract (no trade-in needed).
3. Oppo Find X9 Ultra: Just announced at MWC. Is it worth waiting for the "Very Soon" global release?

Is the €760 deal for the S26U too good to pass up, or should I jump ship for better hardware?
