at my current place, we started off with kustomize. I rewrote everything into helm, which was good initially (at least you can force inject some common params, and others can include this in their charts).
But people (including me) were unhappy at yaml reading; I also grew to hate it with a passion because it's neither go nor yaml, and super difficult to read in general. We are a typescript company, and https://cdk8s.io/ has been great for us. We can unit test parts of charts without rendering the whole thing, distribute canonical pod/deployment/service definitions, etc.
In all of the cases, we combined this with config outputted by terraform, for env specific overrides, etc.
