I've used both - with having to use CF to create a particularly gnarly and sprawling environment. I constantly ran into limitations hidden behind cryptic or unrelated error messages. It was infuriating.

Terraform syntax is definitely not sexy, but it's a robust piece of software, and in fact, can be used to learn better Go techniques.

A total aside, but people who claim Golang is easy are full of it. It's an extremely hard language to write well at scale, and Terraform is a good example to study.
