Your LQS should be able to give you a lot of information on the different batting they sell. I live in a warm climate so I usually buy a low loft batting such as Warm and Natural. I have made quilts with a higher loft when I hand tie them and they are soft and fluffy to cuddle up with. The batting pretty much depends on the project. I use fusible batting when I am making totes or purses. You could also go to You Tube and search for different battings. Good luck.
