EnTT gives you a large spectrum of tools with different trade-offs so that you can tune your code based on usage patterns. Obviously different bits of code will have conflicting access patterns, so there's no one-size-fits-all solution, but EnTT lets you optimise the patterns that are most important to you (based on profiling, hopefully).
