I have some stila stuff
I have 5 eyeshadows:kitten, wheat, mystic golightly and heather. I find them to be of good quality and the price is good especially considering the pans are larger.
The tinted moisturizer: It's OK but it's very sheer.
The mascara gave me fallout. Like black specs on my cheek after a while.
The convertible color in peony is really nice.
I like the one lip glaze I have which is "ulta mate" I like the smell, the color and formula overall.
In conclusion I think Stila will forever be a go-to brand for eye shadows, they really seem to be good in quality and color. Mostly they are very wearable.
