It's a build for Devs, not every day usage. You won't have the stability of even an RC. Expect bugs, don't complain about them.

Samsung has been zipping off with every update, be it Beta, Features or Security Patches. Don't know what made them this fast, I guess the CEO put fire on the software engineers' seats.

nah, stock android have nothing to optimize fold form factors. multitasking on OneUI is great, three way multitask with one additional floating widgets and persistent taskbar on the left side is something that stock android cannot provide.
