Every tool is flawed and picking the right one for your problem is about weighting tradeoffs, that said tools with large well-run communities, the right corporate sponsors and contributors, and enough tenure to round out the sharpest edge cases, are generally "better".

So Terraform and Ansible come to mind. Both deeply flawed, but they become the least-worst current option.

People should still strive for better, test new ideas with new tools, but choices for production code should play it safe almost every time.
