Do DO doctors use OMM frequently?

I believe the main difference between the DO and MD degree is the teaching of osteopathic manipulative medicine in DO schools. Do DO doctors use this a lot on their actual patients? Is it appreciated and useful for patients such that they would prefer going to a DO over MD docs just for the OMM? I don't know much about OMM so I am trying to get an idea of what the training entails and the extent it is used for.
