6to4 in WAN connection

This is a difficult question. My IPv6 router supports 6to4 in WAN connection and therefore I can have IPv6 addresses assigned by SLAAC + Stateless DHCP in the LAN side.  Will PCs in the LAN side associated with the router give IPv6 higher priority than IPv4 when accessing dual-stack websites.  My past experience is that for end-point 6to4 address assigned automatically in Windows 7 PCs, the IPv6 connection has a lower priority.  I will find out the answer as soon as possible.

Most IPv6 stacks still puts less preference in relation to IPv4s on the 2002::/16 prefix. Win7 still does it for one.
