The Griffin Survivor Core and the Thule Atmos X3 are my two favorite slim protective cases for the iPhone 6 Plus. Until recently, it was difficult to compare the two head to head, as I only had one iPhone 6 Plus to put them on, but my husband finally upgraded to the 6 Plus a few weeks ago and chose the Survivor Core to protect his phone, giving me an opportunity to do a direct comparison between the two cases. So which is better? It really depends upon your needs and personal preference. Both cases are absolutely excellent. But here are the areas in which I compared them, and the results:
Thickness: Winner–Griffin Survivor Core
The two cases look like they are almost the same thickness, but this is deceiving as the clever beveled design of the Thule Atmos X3’s sides make it look thinner than it actually is. Both are amazingly thin for the 2 meter drop protection that they have, but Griffin is the clear winner here.
Width: Winner–Griffin Survivor Core
As a part of its protective design, the sides of the Thule Atmos X3 bulge out slightly in the middle of the case. The Griffin Survivor Core’s sides most decidedly do not.
Height: Winner–Thule Atmos X3
Because the Survivor Core’s corners flare out slightly, this pushes it to be slightly taller than the Thule Atmos X3. It is a very small difference, however.
Port Cutouts: Winner–Griffin Survivor Core
The Griffin Survivor Core wins here due to: individual speaker holes, versus the single cutout on the Thule Atmos X3 and a lightning jack cutout that is large enough for many third party lightning cables.
Button Response: Winner–Thule Atmos X3
The Griffin Survivor Core doesn’t have bad button response, but the Thule Atmos X3’s buttons are easier to press.
Scratch Resistance: Winner–Thule Atmos X3
The Griffin Survivor Core has a beautiful, transparent polycarbonate back that makes your iPhone look marvelous. However, it scratches quite easily. On the upside, as long as you don’t peer closely at it, you aren’t going to notice them when the case is on the phone. However, they are there. The Thule Atmos X3, on the other hand, is remarkably scratch resistant. I’ve been using it for at least 3 months and I really haven’t noticed any scratches. It is a very tough case in that regard.
Grip: Winner–Thule Atmos X3
Both cases are quite grippy, and have the same sort of material on the sides of the case–a nice TPE rubber that makes it easy to pick up the phone from a lying flat position, and helps you keep a good grip on the phone during use. However, Thule’s use of this nice TPE rubber extends on to the back of the phone case, so it is unlikely to slide about, while the Griffin Survivor Core has a slick polycarbonate back which does not offer much in the way of grip.
Warranty: Winner–Thule Atmos X3
The Thule Atmos X3 has a 25 year warranty–it will far outlast your iPhone 6 Plus. The Griffin Survivor Core, on the other hand, has the one year warranty that is pretty standard among good quality phone case manufacturers.
Finally, here is a link to my YouTube review comparing both cases–I think the visual comparison is very helpful:
So which is better overall? You choose! I really like them both, and don’t think you could go wrong with either one.
