All good points and to further what Gints is saying, you do have to take into consideration what skills are prevalent in your organization and / or your community. Where I am at there is not an abundance of SQL Server but there is a ton of Oracle so, you can find Oracle DBA's by the dozen.
Thanks for that insight!
