My first MMU was Sheer Cover. I thought I liked it, but I didn't really know anything about MMU. I thought it was normal for the stuff to come off on everything that touches your face. The worst was when I had to scratch my face... I would get orange gooey stuff under my fingernails. So, ugh.
After that I tried BE. I still think that I like it okay, although I know what people mean when they say it seems to age them. I think the coverage is ok (but I don't really have problems with discoloration or acne) but in general, I think it's a BAD thing if you wash your MMU off your face and suddenly you look a lot younger. :/ The BE stuff is extremely overpriced.
I've just ordered a sample kit of EDM. I found this board through google, and read all the raving reviews about EDM on other parts of this board, but I ordered the samples before I was able to read this particular thread... it seems like there are as many people disliking it as there are disliking BE! LOL. Well at least it's so attractively priced. We'll see how it goes.
