I really like Studio Fix fluid, but I have to put something like Moisturgleam underneath or it's just too "dry" for my dry skin. I really like the stick, but trying to get full coverage from a stick can be tricky because it can look heavy. I like to use the stick and apply it with the 109, then conceal (I use KA SSE) and if you want even more coverage than a typical loose powder would give , use studio fix powder with the 182 brush.
The one downside to the SF liquid is that the colors do not match the other MAC colors. I'm NC15 and the SF liquid in NC15 is much too dark except for in summer when I have color:/
