I take some landscape photos, a lot of horse pictures and tons of DOGS!  I have seen the most sales from Fotolia (especially for dogs and horses), but they only accept about 25% of my submitted images. FT seems to prefer West Coast images of the United States.   I've also had success with Dreamstime, Shutterstock and Istock (definitely have more rejected than accepted at Istock - but the dogs and horses accepted DO sell).  

Bigstock for me has been a DISSMAL failure with animal shots and landscapes (I've had plenty accepted -just no sales).  For small companies I've sold a handful at 123rf, only a very small portfolio there though (less than 50).

Overall, my acceptance ratios are about 50%.  I've been active since Aug. 2008 and I've made roughly $200.  My biggest portfolio is on DT with 169 images, my smallest is at Istock which is less than 25.



Hope this helps.

SS is probably best for anything for most of people but I am not sure if this is sign of good correlation :-)
