Today, I would prefer Let’s Encrypt:

  https://letsencrypt.org/

It is philosophically aligned with the open source software world, rather than act as bait for a company that would prefer to sell you a cert instead.

I’m only aware of one case where you absolutely cannot use Let’s Encrypt, but it also affects the other public CAs: you can’t get a publicly-trusted cert for a machine without a publicly-recognized and -visible domain name.  For that, you still need to use self-signed certs or certs signed by a private CA.
