I have found MM to be on par with CL, but with MM you have a lot of local Prima Donas. It is the big fish in a mud puddle syndrome. Also a ton of flakes. They either do not show up, or when you ask for a release, they will not sign it, even though there is pay involved. I had one tell me I had to give her RAW images. It was a for pay gig, and I had not planned on giving her any photos, but she was the big local, and thought she was entitled to them. I have had better luck hitting up local events, beauty pageants, and meet ups where there are many shooting models. You can setup side deals at the meet ups for a later date, and then you know how well they work.
Truthfully I would rather use the candy van, and chloroform over MM.
