I would say, if you want benefit from the features of BTRFS, then go for it. But you have to read a bit what it can do, and use tools and set it up to get the most out of it I think. EXT4 on the other hand is proven and is a setup and forget experience. I chose EXT4 when installing EndeavourOS, because I read a few things about BTRFS that made me think twice and also I don’t need the features too. So, if you don’t know and have to ask the community, then the best would be to us EXT4, unless you know why you want to have BTRFS features.
