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 I am not a huge fan of how certain packages on apt are a few years old and outdated.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?
It has been for me, however no matter which distro you ultimately choose, on Arch I’d very strongly advice to use btrfs as your file system and snapper with snap-pac for snapshotting. It gives you a relatively straightforward way to recover in case you encounter a broken update. At least if it only breaks to a point where your kernel / tty and snapper are still alive and well.
It’s very easy to set up, but if your really want it out of the box (and even with bootable snapshots), you could give Garuda Linux a try. I’d advice to have a look at the different versions, especially Dr43gonized and KDE minimal. Dr43onized Gaming is very bloated and only good to get to know some cool software imo.
