WHICH AIRLINES DO I CHOOSE? ? ?

Today, I was gathering information about the cost of travel to-&-from India at various airlines. There is a $200 difference between the Singapore airlines and Lufthansa. I am trying to figure out which airline shall I go in for. The only drawback of Singapore airlines is that I need to spend nearly 10 hrs at Singapore airport.... Well ! I have to make quick decisions to get the tickets at their best price.
