I have the Laura Geller balance & brighten baked foundation. It's my favorite mineral powder foundation (and I used Bare Minerals for years). It's very easy to apply, I like the coverage - which you can build from sheer/light to medium/full, and it has a nice satin finish. I also have her fuller coverage powder foundation (double take, I think it is called), although I have not tried it yet. The LG site often has sales, so if you're looking to try it out, keep an eye out.
I wear porcelain in the LG and the color match is pretty good for me (I am MAC NW15, Chanel BR12). I bought "fair" and it was quite warm-toned, so I save it for summer. I apply my concealers first, and then use the LG with a large fluffy brush, just swirling it onto my skin until I get the coverage I want. I do sometimes wear various primers underneath it, but I don't think you necessarily need that. It wears through a full day for me, and looks natural even at the end of the day.
I found it far easier, faster to apply, and less of a learning curve than loose mineral foundations, including Bare Minerals. For me personally, Bare Minerals almost always required a primer underneath, and there was a very fine line between "it looks great" and "cakey/patchy." IMHO powder foundations can look more natural and skin-like than liquid or creams. I know that seems counterintuitive, but I've found it to often be the case. Powder foundation can really "melt" into your skin in a different way. Shelbey Wilson has a lot of good YouTube videos about powder foundations and how to apply them, which might be something to watch. I do think Bare Minerals foundation is an excellent product, and I still wear it occasionally.
Another powder foundation you might consider is the La Prairie Skin Caviar powder. I often wear that one as well, and I find I can apply it even faster than the Laura Geller with a similar technique. It has what I could call a luminous-matte finish (not a flat, dry matte) and it can be built from light to medium coverage. It wears incredibly well and lasts all day. It does have a light fragrance, if that's a consideration - the LG does not. That and the LG baked balance & brighten are my 2 favorite powder foundations.
