My personal favorite is https://vertx.io https://vertx.io because it is a little more transparent in how it works and the Rx abstractions are something I was familiar with when I started using it. Not to mention springboot did not offer reactive programming until fairly recently whereas vertx has been reactive from day 1, rxjava or not. I will take another look at springboot just to see what the fuss is about. I am a bit surprised that netflix did not come up with their own light weight backend framework based on netty.
