The alternative you suggest has a longer chain of certificates, and more difficult setup. Using ZeroSSL is way easier with less bytes on the TLS handshake.

Do you have a test host with the Zerossl chain that you speak of? Use https://aye.sh if you want to try a host using the ECC chain from LE.

So the article is outdated I guess. The length of the chain is the same now.

I'll consider switching back to Let's Encrypt once this setup doesn't require a whitelist.
