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 I am not a huge fan of how certain packages on apt are a few years old and outdated.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?
You should prepare yourself to be the car enthusiast of computer users when thinking of using Linux at all, especially for gaming. You are the car but of computing when you dip into Arch based or other similar distributions. You will spend time looking at parts of the OS most people take for granted and can spend as much time as you want fiddling with tiny bits of the OS to tube it to whatever you want. So really it depends on what experience you want.
