An excellent comparative study of tunnels in V6 against the V4 substrate
was reported to the IEPG back in February 2005 - see Kenjiro Cho's
presentation at on this topic

As far as I can tell the results were surprisingly good - there are 
some outliers, but
in general the tunnel performance largely aligned to the underlying 
V4 connectivity

That was in early 2004 - it would be interesting to see current 
network data using this
