I do not feel that one is a big boost and the other a small boost because wonders are only as effective as you make them. When you are after medals remember you can attack way more than you defend so I believe the old saying the best defence is a good offence fits. The top players have Versailles just to note, not that that should have any bearing on picking Versailles over Angkor, but it clearly shows sucessful players feel Versailles is a better choice as the change wonder option is now here and Versailles is still the choice of the leaders. This game is about attacking and that is the most fun part for me, and no defense is unbeatable, so I myself prefer every offensive boost I can get, not interested in the Angkor switch at all.
