For me, it depends on the feel of the brush itself. I’ve used great brushes from both camps, but I’ve also found scratchiness from both.
It’s all about opaque color in one stroke — I don’t want to have to go back over the same line to fix any unevenness. It should stay on for 8 hours or longer without fading or migrating!
Creamy enough to glide on and deliver opaque color in one stroke without drag but not so creamy that you end up with smudges beneath your eye an hour later. I like twist-up mechanical pencils best, just because you don’t waste product by sharpening.
I personally prefer cream eyeshadows that will set on their own – I don’t mind one that is better used as a base, but in a perfect world, it would set on its own and last all day long without creasing or fading. It would be blendable without drying down too quickly (or staying wet for too long). Medium color opacity would be lovely with buildable color to full color opaqueness.
Can you see a theme in this week’s questions? 🙂 I want true-to-pan color that’s rich and dense–if I want to sheer it out, I’ll use less–that applies smoothly, evenly, and doesn’t disappear once you blend it out. I like denser, richer textures that almost feel buttery and creamy but are still powder-based.
