Speck Candyshell Grip
In short:
Perfect to me despite from the increase in size and weight.
Long winded:
I have the iphone 6 plus, which is just too slippery for me when going caseless.
The Speck Candyshell Grip is almost the perfect case in my opinion for me.
The standout feature that I saw, and everyone that I've shown to, notices is the grip. I can, with confidence, use the phone one handed. I do need to shift the phone around to reach all parts of the screen, but I have no problem finding the grippy strips which really help keep the phone in my hand without sliding.
The buttons on this is super responsive.
The case feels really really sturdy to me too. Speck claims this meets the Military drop spec, so I'll trust that.
The lip is high, but not too high to me. Its rubbery, so I don't need to place the phone down face first really carefully.
The only 2 big negative things to me is the increase in size and weight. Granted the iphone 6 plus is already large, but in certain pants with the CandyShell Grip, its too large. **(I don't wear skinny jeans). With my other smaller, slimmer cases, I don't feel the size as much. While I have no problem with the increased weight, its definitely noticeable to me.
All in all, this is my favorite case. I'll use it for weekends or when going on long trips. For daily use though, I'll probably switch between the Speck CandyShell Grip and my Spigen Air Cushion clear case. The Spigen one is good enough for normal use, but the buttons on mine is much much harder to press and it doesn't feel like it'll protect as much as the Speck CandyShell Grip.
