MySQL, PostgreSQL or MSDE ?

[inoxo]

Hello,

I'm considering using another database server (than Access). The application has more and more users so I would like to upgrade the server to a better DBMS in terms of robustness, security and performance.

The client will remain an access application.

I made my short list but it remains open to include another DBMS : MSDE, SQL server, MySQL, Postgres, ...

Do you have any information that could help me to make the best choice, such as :
- benchmark reports
- compare analysis
- case studies
- your opinion
