Should I use ORM or not?

What are the advantages of using ORM Stack Overflow?
Advantages: 1 Speeds-up Development – eliminates the need for repetitive SQL code. 2 Reduces Development Time. 3 Reduces Development Costs. 4 Overcomes vendor specific SQL differences – the ORM knows how to write vendor specific SQL so you don’t have to.

Edit: You wouldn’t use an ORM for a performance critical situation same way you wouldn’t use .Net or Java to write an operating system. Consider your requirements before choosing. Even if you don’t use an ORM, you will end up doing some mapping yourself either via repeating a lot of code or by using a data dictionary.
Do you need an ORM to write SQL queries?
