Yes, you are better off.  If we rely on GeoIP at the DNS level and a
user's recursive DNS server is far away from them then we may pick the
wrong mirror.  But if we do it through a redirection or indirection at
the HTTP level, then we will pick the right one.  If they are using an
HTTP proxy far away from them, they will surely be using the same proxy
to fetch the files they wanted, so a mirror close to the proxy is the
right answer.
