Pros
- SQL Server is a robust and fully-featured database, and it performs very well. Moreover, I have not had any problems using this database with Python.
- The SQL Server Express versions are free to download, use and can even be redistributed with products.
Cons
- Windows only.
- SQL Server comes in various flavours. The regular version includes the GUI tools and also provides advanced features which are not included in SQL Server Express.

mxODBC requires an ODBC driver to talk to SQL Server. On Windows, this comes with SQL Server, on the other platforms, there are several commercial ODBC high quality drivers available. There's also a FreeTDS ODBC driver which is free.
Unicode is supported both for data and SQL statements. mxODBC supports both 32-bit and 64-bit platforms.
ODBC
It is possible to connect to an SQL Server database using ODBC, either the mxODBC driver or the one included with Win32all. However, this is not recommended - adodbapi is a better solution, in part because it supports unicode.
