I have been using Mat Lumiere compact for a long time now (this might me third or fourth refill) in 10 Lumiere. During the year, I use it on top of Mac Studio FX foundation (during winter months & when going out), on its own (warmer weather) and for touch-ups during the day.
I think I keep repurchasing for the combination of GREAT packaging, solid quality and because it usually gives a good balance for my mixed skin: it is not dull, as many mat powders can be on the skin and for most of the time provides the nice, glowy-mat appearance its name promises. Used on its own, it has medium coverage and I am usually happy with the slight soft-focus effect it leaves on the skin.
However, it not a perfect compact for the summer, at least for me. My T zone becomes oily very soon after the application (in spite of using matifying base underneath it) and I need repeated touch-ups on and on during the day.
So, I am now looking for something else to get me through the summer heat, but will probably get back to it in autumn.
This probably isn't the best compact for me out there, but I still haven't found the better one.
