I am not the person you asked this question to, but I would probably do the same so I will answer:
Once you get used to it, it just makes managing things simple if you always use it for everything. I have a personal harbor service that I run on my local cluster that has all my helm charts and images, and i can run a single script that sets up my one node cluster, then run a helm install that installs cert-manager and my external-dns, and now I can deploy my app with whatever subdomain I want and I immediately get DNS set up and certs automatically provisioned and rotated. It will just work.
