I started out with the Ringke Slim and loved the look and feel, but eventually got frustrated with how hard it was to remove. It felt like I was about to break off my power button trying to flex the Slim over it. It also had a slightly sharp edge that I'd occasionally notice.
I ordered the Poetic Palette and love the texture, fit, and look. Still very slim, but much easier to remove for cleaning. I'm definitely happier with it.
