Been on One UI 6.0, Android 14 Beta on my Fold5 for 4 days now and am loving it.
Very early results are showing a noticeable improvement on battery life and I like the new battery app. Also the expanded Control Panel with a single swipe and the ability to configure Airplane Mode, (see previous posts).
I also like the new font and emojis but perhaps best of all are the camera improvements for Quality optimisation and the camera widget settings to quickly open your camera settings of choice, (see video), not to mention the new, configurable, watermark settings.
Also, check out the new Gallery, editing tools and Samsung Studio.
