I can say that from my small corner, something has really improved.
In Abril, when ipv6.google.com was launched, the avg latency from my
network was about 140% higher when comparing to www.google.com.
*Now* it's about 10% *lower*! (about ~5ms in absolute values). So, someone
tweaked something, somewhere regarding v6 routing :-)
IMHO, this also may indicate that there is still something along the
path in the v4 side which may need some tunning... ;-)
