Ansible vs Terraform for idempotency?

This post assumes all of us are familiar with these two tools for infrastructure provisioning and configuration. This has been bugging me for a while. The shop I’m at is in hybrid cloud setup and I’ve been using both of these tools and finding out how terraform is becoming redundant slowly. Both of the tools are sold for their idempotency for provisioning and configuration.

Terraform handles idempotency using statefiles with a persistent data store.

Ansible handles idempotency with “gathering facts” in memory and avoid any drift.

Pardon my ignorance as this might have been ask in another angle in this sub. But why would I choose terraform over ansible for infrastructure provisioning at this point with the hassle of handling persistent statefiles when I can just do a dry run of ansible to see the state of my infrastructure all handled in memory?
