Which are more widely supported by browser clients, wildcard or SAN certificates?

I need to decide between using a SAN cert or a wildcard cert. Client/browser compatibility is my biggest concern.

Digicert maintains pages for compatibility with certificate types:


SAN certificate compatibility
Wildcard certificate compatibility


They note several server side compatibility problems with wildcard certificates but no client side problems. SAN certificates are problemic for some older browsers:


Versions of major web browsers from before 2003.
Older smart phones running Symbian OS
Older Palm Treo


If supporting these older browsers is important to you, then wildcard certificates have wider browser support.
