> If you have "base, and then we change three things per environment", Kustomize is about as good as it gets using simple patches.

Real talk, I could not for the life of me figure out how to use Kustomize. I spent a day or so poring over the documentation, and while I could recreate their hello world type examples, I couldn't figure out why they worked or how to make it work for our needs. Meanwhile, Helm immediately made sense and I had a chart banged out for the software I was trying to set up in under an hour.

I'm sure someone will tell me it's a skill issue, but Kustomize was simply way harder to use than Helm (or the documentation was worse, not sure which). So we wound up using Helm.
