I made a post a few days ago asking your opinion on Manjaro and it was very mixed, with a slightly negative overall opinion. I heard some recommend EndeavourOS instead and did some online research and it seems to be pretty solid and not have the repository problem that Manjaro has.
Just for context I am a Linux noob and have only used Mint for about the past six months. While I don't have any major complaints, I am looking to explore more distros and the Arch repository with its rolling releases. I am not a huge fan of how certain packages on apt are a few years old and outdated. However, I also don't have the time to be always configuring my OS and just want something that works well out of the box.
Is EndeavourOS a solid choice?
I've been using EndeavourOS for about 1.5 years on my laptop and about a year on my desktop. I've been using it as arch but pre-configured. I believe EndeavourOS uses the same repositories as stock Arch, with an extra EndeavourOS repo added for theming and some convenience tools they use.
The UI might not be as easy as Manjaro (I don't think they pre-install a GUI for pacman/yay, but it isn't hard to install one like pamac). Other than that if you use a desktop like Gnome or KDE and install a pacman frontend you probably won't need to interact with the terminal more than you want. Honestly I think EndeavourOS is a great place to start if you want to learn more about Linux without having to spend the time configuring your system from scratch.
