WDM is designed to be shared between multiple hosts.

ASIO, unless is is the newer Multiclient ASIO, is not.

However, using WDM may result in a higher latency value than when using ASIO. This may or may not be important. If you are using software based synthesizers in realtime, attempting to play them on a keyboard or other MIDI instrument, the program in which you are doing that would likely work better using ASIO drivers.

There is no audio difference between the two, both make the same identical pcm digital audio.
