I have used both programs and have found MDX to be more user friendly with input and output. Additionally, I have had good comparisons with both programs against each other and with GTSTRUDL.

RE: Descus vs MDX
I have just finished a month long evaluation of a bridge that was designed with an older version of MDX. I used Staadpro 2003, MDX Version 5.98, and current Descus I. Staadpro 2003 got the best results, then MDX, and last came Descus. I used the high resolution finite element option on MDX and just used Descus which ,I think, does a grid analysis only. The main differences occurred in the Live Load output of the programs. One item that bothered me about Descus I was that lane loading produced a higher than expected girder stress at midspan of span 2 which was only 79 feet long. I modelled the lane load on Staadpro and got only about .5 of the moment due to the truck. MDX has worked with me to get the newer version 6 debugged; so I am staying with MDX for steel girder design.

I wouldn't buy any of them.
MDX graphic interface is really terrible. It use simple rod elements but they call them "finite elements". For programs like this, Aeronautical Engineers call us “low tech engineers”.
Stick to a real engineering program: SAP2000 or GTStrudl.

RE: Descus vs MDX
Thanks for everyone's input. I should have been more specific in my original post. I was looking for input of MDX vs Descus II for curved box girders. I had used BSDI in the past and was investigating other programs. After using Descus II on a trial version, I have concluded it is not for us. I would pick BSDI over Descus II anyday.
