Lately, I am preferring libraries over DSLs more and more. As I have ventured into learning Rust, it seems that all too many Crate authors abuse the (otherwise awesome) macro-system to create their own DSL. If more library-developers spent their time on designing a well-put-together API, then I would have the benefit of everything else my IDE supports:

• Syntax I am familiar with: nothing else to learn besides the API surface
• Autocomplete for discovery! (instead of switching between a Docs page and my text-editor)
• Inline documentation, if methods were documented
• etc.

The epitome of this philosophy would be RethinkDB's query language, which is actually an API, and not its own query language!

What do you all prefer?
