Comparing bluebird and promises is like comparing squares to rectangles. It's a superset. One benefit of bluebird is having specific catch blocks for specific types of errors. You can have certain errors handled by the catch while other errors bubble through. This is also possible (and cleaner) with async/await though. Bluebird also adds a bunch of operators for racing promises a d and polyfills for other things that might not be available in your runtime. I'm not saying to use bluebird, I definitely prefer native implementation, but there are still contrived use cases for bluebird
