S25 Ultra vs. OnePlus 13 vs. OnePlus Open (for shits n giggles)

I just posted here a couple weeks ago but I've turned a complete different direction on what phone I want to upgrade my base S23 to. I decided I don't wanna deal with Xiaomi's HyperOS. After some research online, I can get any of these phones for basically the same price, so now I'm just tryna get some help on finalizing my choice. I'm also open to different suggestions as well of course, as long as it's around the $700-800 USD range.
