Pretty much same here. With Spring stuff I still use YAML because TOML doesn’t have first class support yet. If TOML is an option I don’t have to go too far out of my way for them I go for it.
YAML has too many foot guns. It’s still less annoying to read and write than JSON though. Properties files are okay but there doesn’t seem to be an agreed upon spec, so for edge cases it can be confusing.
