Should I Use OpenTofu or Terraform for My New Deployment Environment?

Hey everyone! I've recently started a role where my company focuses on a SaaS platform along with customer-managed installations across various cloud providers. We're setting up a new platform entirely in Azure for the first time, and I've encountered some real frustrations. Ansible, which we've been using to manage our infrastructure, has a lot of missing features and bugs for Azure, so it's clear it's not the best fit for Infrastructure as Code (IaC). I've convinced my boss to allow us to build a fresh deployment environment using either Terraform or OpenTofu for IaC, with Ansible for configuration management. However, I'm not experienced with either tool. Given my situation, do you think I should go with Terraform or OpenTofu? Have you switched between them, and what influenced your decision? I'm not looking for generic comparisons but rather real-world experiences. Thanks!
