The weekly ROM is a beta, ie. it tends to be more experimental than the stable version. It occasionally does not work absolutely correctly. In these weekly threads we exchange our experiences, when things do not go right, and can offer help or advise when it is known.
The stable version is not normally as advanced as the weekly beta version, but, as the name suggests, any difficulties are normally ironed out to give you a trouble-free experience of (in this case) the latest Android version with many of the features of HyperOS.
You will also have to take into account how you use your phone and whether you need a trouble-free system, or whether you are happy to accept the challenge of a beta version with the occasional problem.
The final choice is yours.
