Thanks.
All the distros you listed have their audience and cater to their needs. EndeavourOS markets itself as terminal centric and ArcoLinux is for those who want to learn Arch Linux at different levels. I presume that some forums and groups will expect a certain level of skill at using Linux.
RebornOS wants to be beginner friendly and GUI friendly. We have no branding on our desktops. We provide (of course free for everyone 
) live assistance on Discord and this is where most of our users are. We are developing optional GUI applications to help users: RebornOS FIRE, RebornOS Welcome, one-click mirror refresh, and a rescue application (planned). We’re also exploring using the Calamares installer for supporting less common storage and filesystem setups.
