What do you mean by easy? Amount of code to write? How easy it is to understand? Performance?

And what do you mean access? read? write? add? delete?

You did not answer my second question. The different array kinds have different performance impacts depending on your intended use. For queue and dynamic arrays, see: [why need dynamic array | Verification Academy](https://verificationacademy.com/forums/systemverilog/why-need-dynamic-array#reply-56627)

Associative arrays have very different use models; mainly for non-contiguous indexes.
