The real MME is a pretty dead horse. However, the implementation that says MME in BIAB is actually WDM. They just never updated the term as used on that screen.

WDM can work very well, especially if you want more than one program to access a soundcard at the same time (although I understand Steinberg just removed that limitation in ASIO). For most soundcards, unless the manufacturer says differently, a user should test both ASIO and WDM and choose whatever works better. Don't feel bad if that is not ASIO. The main reason ASIO should be chosen is if you are interested in getting the lowest possible latency during recording.
