EV certificates have the same level of confidentiality and integrity as DV certs, but they have different authentication - specifically, they tie the certificate to a legal entity rather than a domain name.

ie.

    https://paypal.com-customerservice.ru

vs

    PayPal Inc [US] | https://paypal.com

I run https://certsimple.com. We sell EV certs. But you can verify the above pretty easily by checking out the EV guidelines, the additional requirements that apply only to EV certs (https://cabforum.org/extended-validation/). You can also see the difference with openssl pretty easily:

Here is a DV cert:

    openssl x509 -in domain-validated-example.com.crt -noout -text | grep Subject
     OU=Domain Control Validated
     CN=example.com
     DNS:example.com

Here is an EV cert:

    openssl x509 -in extended-validated-example.com.crt -noout -text | grep Subject:
       jurisdictionOfIncorporationCountryName=GB
       businessCategory=Private Organization
       serialNumber=09378892
       C=GB
       ST=City of London
       L=London
       O=example Limited
       CN=example.com
       DNS:example.com -
