Bottom line for the extra connectivity and DLNA certification i would go with the
Bravia Z-Series KDL-40Z4100/B 40-Inch 1080pBecause if you connect this to your in home network you can stream music videos and music off you PC onto your TV without the need for extra wired or memory cards etc.

Otherwise if you don't need this feature the other options are identical on the other TV so it is just as good a choice.
