I am developing a couple of projects that will be using a backend database. Without the cost/free argument, what are the pros and cons of SQL SERVER vs MySQL? I'm familiar with SQL Server, so I naturally lean towards that, but I want to be able to make the best decision between ASP and PHP (different thread!)...I basically want to know the goods and bads of each.
Would major companies rely on MySQL considering the opensouce roots? Is it reliable?
