I use both in conjunction. There are Ansible modules to run terraform, for example. The biggest issue for me is that Terraform is still pretty bad at looping and handling dependencies sometimes. They have ways to try to work around it, but sometimes it's much easier to say "Do X, then Y, then Z". With Ansible, I can explicitly set the step order, and even write a quick module if I need to interface with an external API.
