I have been using Let'sEncrypt in the past, for me it always felt like a struggle since im hosting on Windows server, the automatic script's didn't work (mainly because lack of kowledge) and i didn't have time to update 10+ sites each month just to keep their SSL certs fresh, i just bought Comodo SSL for my customers and it ended well, now i don't even have to think about it any more. ^^ next refresh in a year.
In the past, I bought my own SSL Certs from ssls.com however since cPanel integrated Let's Encrypt as a default option for SSL Certificates for accounts, it was much easier and I let them lapse when renewal came. I've recently moved off to a VPS running Webmin / Virtualmin and since it has let's encrypt support, I've been using that for sites that need it. It just makes life a whole lot easier, and cheaper. Donated to their cause a couple months ago.
