Why are you looking for another provider? Just use Lets Encrypt ;-)
Let's Encrypt doesn't offer EV certs. Which is reasonable; EV certs can't be automated (and they're a dumb idea anyway), but they're still necessary for some of my sites.
No entirely, but mostly: seeing as this is my job, I should have some idea. Currently writing a post about how we've used some psych techniques to automate the non-automatable parts which I'll post on HN.

EV matches identity to public keys. Nothing more, nothing less.
If you need EV, we (https://certsimple.com) specialise in making those background checks far less painless with a bunch of unique tech. This means you get your certificate faster and with a lot less effort on your behalf (and a lot more on ours) during the verification process: https://certsimple.com/about
If a DV cert is fine, go with Let's Encrypt (Hi Richard!), dnsimple (Hi Anthony!) or CloudFlare (Hi John and Filippo!) or Heroku.
