Both signature and everyday minerals are great brands. As far as foundation is concerned they are equal in my mind, but EDM does have wider range of selection. EDM also has the intensive, semi matte, matte, and glo options whereas Signature has one semi matte formula. But the quality if about the same. I would order a smaple kit from both companies and see which one you feels suits you better. If you get a finishing powder from Signature, get any of them except the Translucent. (the translucent powder is weak, but the rest of them are good)

Eyeshadows; Signature has amzing eyeshadows. They last all day and they have gorgeous colors. I haven't tried EDM's yet so hopefully someone else can help you there.
