…dex jump, however your included example of ENTT is not one of those poorly made implementations and it constantly benchmarks faster than archetype implementations. Combine that with EnTT group iteration of components doesn't need to test each archetype set to see…
This very much depends on which benchmark you pick. I did quite an extensive benchmark comparison between Flecs and EnTT, and they outperform each other in different areas: https://github.com/SanderMertens/ecs_benchmark
I am not trying to start an argument over which model is better. In fact, I am a big proponent of hybrid models- and I think I have been pretty upfront about the disadvantages of archetypes in this post.
