It's true, they're similar. Quarkus leans a bit more towards Java EE, Micronaut a bit more towards Spring. I don't think it would be worth switching from one to the other.

Cool, thank you! I've never seen Quarkus before so it's new to me, but I've had some success with Micronaut so I was a little confused. Surprised they don't work together; the goals do seem very similar.
