I've used MUFE for years and here are my favorites:
Star Powders, I love the iridescent finish, the black one is to die for and you have a huge color selection, plus they'll last you quite a while as they are super pigmented. You can add Star Powders to foundation, lip gloss, mascara for a special sparkle and highlight.
For unbeatable shine, their Diamond Powder, it's microfine glitter and if you like sparkle and a dramatic look, these babies are for you, you can also add it to lip-glosses if you like glittery lips or add it to your lashes immediately after putting on mascara for even more sparkle.
I love all their foundations, my favorite is Mat Velvet + (I tend to prefer matte finishes on foundations), although their Lift Foundation is also incredible and if you like a sheer foundation that just unifies your complexion, Face & Body is great.
Their primers are great and their concealers are super pigmented. Try the lift concealer for your eye-area, if you have dark circles it will illuminate the area and you won't have to put so much of your regular concealer.
The primers and color correctors are incredible, but if you have acne-prone skin proceed with care, they have caused break-outs in the past, for sporadic use, their OK though.
Their powders are also great, Super Loose Mat Powder is great, specially if you have combo/oily skin and their Shine On Powders are completely wearable and don't have a trace of glitter, just a pearly finish that can be used to highlight or it's fabulous for all over every day use for super dewy skin.
If you like to contour, then get their Compact Modeler, the shades are great (although it favors light to medium skin tones).
I like their lipstick palettes and if you want to build a lipstick collection, it's the way to go, plus they have refillable palettes for lipsticks as well.
Gloss wise, I think you have better choices out there, they're OK, but not the AWESOMENESS of their other products.
What I really don't recommend are the mascaras, they're just not worth the money.
This is what I can think of, off the top of my head.
