Allison,

The only feedback I ever found about the Taj Mahal was how beautiful people thought it was.  Remember that Shah Jahan built it at the height of the Mughal empire.  Louis XIV built Versailles during a time of great poverty in France.

In addition, the Taj Mahal was actually finished.  Versailles kept on going ~ no end in sight.  Maybe that would have made a difference in France?  I reckon probably not.  I think Louis XIV and his nobles would have found something else to spend their money on.
