I got earlier this month base S23 at this price point(510).
I also saw a fiew days before Z Flip 4 around 500.
These are probably the best Samsung devices you can get, if you find them around this price.
Between 400-500 i dont think any Samsung device is that great tbh.
There is a reason more storage options are available.
You should have bought the 512gb S23U, if you wanted to shoot tons of photos and especially 8k videos, what exactly did you expect???
