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 I am not a huge fan of how certain packages on apt are a few years old and outdated.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?
Endeavour is fairly easy to run and maintain, aside from not having a GUI package manager installed by default (I say this as someone who has been running it for about 2 years now, and still considers themselves a Linux noob)
One underrated feature is the Welcome tab, which also notifies you if there's some critical error in the latest update so that you know to use caution and take certain steps when updating
Other than that, running
yayorsudo pacman -Syuis most of the maintenance you'll need to do
