I actually don't think there's going to be much of a difference in price, last time I checked, but that was a few months ago. The big new feature list for S24 is primarily AI stuff related to things like translation and photo taking, if you don't care about that it really doesn't matter which you get. I'd say to go with the S23 if it's anything more than $100 cheaper.
Technically, the S24 does have a new tier of chip, but considering my S23+ can play Wii and 3DS games without hiccups it's really not necessary lol.
