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 I am not a huge fan of how certain packages on apt are a few years old and outdated.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?
As someone who's used it for at least 3 years, go for it. However, it requires lots of configuration to get it the way you like it, so openSUSE Tumbleweed is probably the better pick for you.
It also comes with cool utilities like
nvidia-inst(archinstalladvocates, write that down) and the community's great too.
