Purely personal notes...
MySQL is good, and you get alot for the money when you buy the licence (as you mention commercial usage). But, it does not (yet) support Views, Procedures and subqueries to the fullest as for example MSSql.
MSSql on the other hand is a Win32 platform solution. But as an experienced MSSql user I can vouch for that it's very good, and you can link it to *nix solutions. It's Enterprise Manager is also an easy to understand and graphicly can help you build tables, views, queries etc. It comes with a db-monitor that as a db-administrator heps you alot.
However, the heavyweighter Oracle practically 'wrote the book' so to speak, supports most you can think of in the sql language (everything mentioned above), stable as a brick on a flat surface, but costs mucho dineros.
So as Mac said, try to find all benchmarking tests, but also don't forget the economic issue.
