For a start theres a basic comparison on this page:

http://www.cisco.com/en/US/products/hw/modules/ps2797/products_data_sheet09186a00801df1d9.html

Major differences that it points out seem to indicate that the FlexWAN  
is of medium performance, whereas the Enhanced is of high performance  
(2 x packet forwarding rate).

You should be able to draw your own conclusion from that page.
