I really do love the Apple Leather case. It's very simple and professional while not adding any unnecessary bulk. It's not the best at protecting, but it damn sure looks the best.
Does the Apple Leather Case add grip to the 6 Plus? I have kinda small hands at it's extremely slippery and dangerous trying to reach the opposite end of the screen. If it adds grip and makes it safer to use, I'll keep my 6 Plus.
Currently have the pelican protector. It is very strong and does not add as much bulk as you might to, returned both the leather and silicone and they were both nice but too thin and slippery.
