I too go with Oracle. Oracle Database is far better than Sql server. Sql server is easy to use, But oracle is the best, Most of us are using sql server is because the cost of Oracle products is more compared to sql server. Sql server can support only windows whereas Oracle will be supports for multiple platforms. Sql server is easier to install and manage. Oracle is difficult to install.PL/SQL is powerful than the T-SQL. Cost is the major factor why many companies and client are not using Oracle products.
