There's nothing to be gained by picking a winner, especially if it doesn't really matter because the important APIs are the same.
Newer frameworks like Quarkus are specifically built for container usage and applications built with it are a bit faster and smaller than Spring boot.
I'm saying the spec lost to Spring. There are many historical reasons for the loss, but Spring won.
It looks like the industry is moving away from architectures like EE. The desire now is more like a Go deployment: single, self contained deployable. There are make frameworks that support this goal. Maybe EE is one of them, but it's not essential like it was in the early 2000s.
