As my experience about beta version of Flyme OS 6Global and China

first of all i will choose Chinese version because its give more stable and smooth working condition for my device especially its working with VoLTE
second one chines beta gives you achance to download a lot of Themes, wallpapers and Musics its not available on global beta

Third one it gives you better battery back up as well as good ram management with out any issues with google apps

Fourth one  Drive assistant is provided by chines version not available on Global beta version
Last one Camera Features will surprise you as well as its image quality


but important problem for Chinese version it is pre installed with some unwanted apps and you can't uninstall that apps

Global beta version of Flym 6 gives you much better experience than Flym 5 in terms of battery back up, RAM management and Gaming but its still not supported by VoLTE it is huge setback for customers from India

In My opinion ig you want a good experience with beta version you go with chines because its amazing than global beta vesion
