Not sure if there is a point to "keep things in Europe" when it come to certificate authority.
- LetsEncrypt don't have the private key tied to your certificate
- Any of the Certificate Authorities could potentially emit unauthorized certificate
Your only protection for all of these problems is HPKP. If you prefer to keep things in Europe, keep that pinned private key in Europe, but the rest doesn't matter.
That said, it's pretty nice that LetsEncrypt forced the ACME protocol on this industry. Not only it create redundancy with mostly interchangeable alternatives but before ACME, there was no way to fully automate certificate provisioning cleanly.
