S24 if you want Spen with Bluetooth. I went S23 to S25...before realizing S25 has 0 Bluetooth, which I loved for taking pix.
Even though 25 had brighter screen, I downgraded to S24 and am much happier with the Spen.
I was also not super happy with the 25 rounded corners which made phone seem smaller and looking too much like an I phone. I'm probably the only person who liked the sharp corners.
I also love the S24 Ultra design. The maximum brightness is actually the same. Try tapping and holding the brightness slider and turning on Adaptive brightness or Extra brightness.
