We are updating our wildcard certificate and see that we have the option to use both RSA or DSA with Symantec (for free), while Digicert offers 3 options for wildcards ECC, DSA and RSA.
Is there a compatibility matrix for which browsers support ECC? (or the others)
We only support TLS1 and newer, so this may make ECC support easier

Based on my research, Network Solutions, and GoDaddy only offer RSA. No DSA or ECC support. Comodo supports ECDSA curves secp521r1 secp384r1 prime256v1
Symantec Wildcards don't support certificate transparency at this time
