I plan on making the switch too, I have the Pixel 7 Pro and have an S23 Ultra pre-ordered. I've typically preferred Pixels over Samsung until I got the S22 Ultra. I was pleasantly surprised by that phone, but ultimately I was persuaded and intrigued by the 7 Pro (and kept telling myself "I'm a 'Pixel guy'" LOL) so I got the 7 Pro and sold my S22U. I find myself regretting that more and more as I really enjoyed what Samsung offered with the 22 Ultra.
While I don't have the S23U yet, I am willing to bet the post above mine regarding point and shoot camera shots of kids and pets will be better on the 7 Pro. That was the case between the 7 Pro and the 22U and every Pixel vs Samsung since the 1st Pixel. That was the big draw for me to the Pixel line, however, my life has changed and I found the S22U camera to be more than capable for what I needed. My kids are older and now hate taking pictures LOL and I've also learned that pics of your pets that are slightly blurry or lack fur details don't matter all that much when they're no longer with you; you learn to love any pic you have of them because you just miss them being around.
