Can I ask this question here? It was closed on stackoverflow.com as being off topic.
Not really. This is a site for questions about user experience, so your question would fit if it were along the lines of "which is easier to understand?", but the question as it stands is "what is your feedback as a developer". So you'd need to rewrite it to be about the usability of the API if you want us to accept it.
The fact is that usability of an API is kind of a gray area. You end up touching on information design, programming, UI design, and basic writing. No SE site that covers those topics really exists.
