I love the rose gold, and I love clear cases, so it's a good combo for me. I also have a turquoise Apple silicone case, and I switch out depending on my mood.
I use the VarioProtect in the semi-transparent color and I've been pretty happy with it. I wanted something clearish that also had a stand and this was the only case that really fit the bill. It's nice to use the stand to prop it up on the table sometimes when I wanna keep an eye on my notifications.
I finally capitulated to the Rose Gold this morning after being ostly on the fence. I truly am my own reverse psychologist.
(good lord I really need to spell check~)
I have the Apple black leather case on my rose gold 6S+ and my Gold 6+. After using the 6+ with the leather case, there was no doubt in my mind when I ordered my 6S+ that I would get the same leather case with it.
I got the rose gold to easily tell the difference between my two iPhones.
