That is indeed a technical difference. But I don’t see much significance in it.
Spring is a de-facto extension of the core java libraries and alternatives like Quarkus follow the same mental model with a better technological foundation.
Maybe, but with all the modern .NET tooling I feel at least 2x productive in .NET than in Spring Boot. There are a lot of quality of life stuff in .NET/C# that really does add up and makes a substantial difference (DX-wise) in the long run.
