Depends.  If opendns already has that entry cached, then it's one stop
shopping.  If it's a new query, the it would be marginally faster for
you to hit the root servers yourself and recurse through the DNS tree.
Remember too, that once your server gets a reply for somedomain.com,
that it will be cached locally so there won't be any further remote
lookups for it.  At least until it expires.

Personally, I don't think it is a significant difference either way.
If, however, you're running an older version of bind or other DNS server
that doesn't do random ports, and you don't have the luxury of upgrading
in the immediate future, using opendns as a forwarder will add a layer
of protection...
