+Spring - dominating the Java world
+
+- well established
+- reactive stack with Spring WebFlux (since v5)
+- biggest community
+- most integrations
+- multi language support
+- heavy use of reflection
+- support for GraalVM (beta)
+
+
+
+Quarkus - cloud native framework
+
+- reactive stack
+- minimal memory footprint at startup time
+- based on standards and frameworks
+- GraalVM / serverless cloud functions
+- slower compilation time (AOT)
+- smaller community as Spring
