For those interested, here is my OTTERBOX COMMUTER vs CASE MATE TOUGH comparison. I now own both of these cases and found some interesting differences.

OTTERBOX COMMUTER

+ Very solid case 9/10

+ Rubber has extra cushioning bumpers on corners to better protect against drops

+ Cutouts also have secure plugs to prevent dust and water from intrusion

+ top, bottom and sides have hard plastic protection over the rubber making a more secure fit all round.

+ Rubber is of a higher quality 8/10

- Sound quality of speaker phone is slightly affected by the raised plastic that sits closely around the speaker. Sound comes out a little louder and sharper but still sounds fine.

- Case can be quite difficult to remove because the plastic cover sits over all four sides and is very tight

- Plastic cover surface is very smooth and nicely designed but will be slippery with oily or sweaty hands

- Screen protector cutout is a little short near the top where the earphone is compared to other screen protectors I've used, but quality is fine, average.

- headphone and charging ports are a little smaller than I'd like but should fit most accessories.

- ON and VOLUME buttons are a bit difficult to press, quite like most TPU cases

- Having plastic covering on the front sides, it can be easily knocked off a table when sitting face-down, and back down is even worse.

CASE MATE TOUGH

+ Very solid case 8/10

+ headphone and earphone ports are a perfectly cut to fit all brands.

+ Very easy to remove with only sides covered by plastic cover

+ Plastic material has excellent grip on sides and back making it much more secure in the hand.

+ Plastic is less likely to show scratches over time

+ Quite easy to remove with only the sides cover the the plastic cover.

+ ON and VOLUME buttons are very easy and nice to press, with perfect feedback, almost a little 'too' easy actually.

+ The entire front is rubber, so when sitting face-down, it does not move and has a secure grip on surfaces, less likely to be knocked of a table etc

- Because the plastic cover only sits over the sides, the top and bottom have the rubber exposed and it could catch on things, such as removing from a tight pocket. not a huge deal in use.

- headphone and charging ports are open and exposed.

- rubber is a little thinner than the Otterbox's and more stretchy/flexible, though may not be a big deal in use/drops.

So in conclusion, I really like both cases for different reasons. At first impressions, the Commuter appears to be the better case due to it's port covers, more secure fit with plastic covering all sides and the extra protection given to the corners of the case.....BUT....

....the Tough case just feel better in the hand, more secure. While both are almost identical in size, thickness and weight, the Tough has a nicely textured hard surface (that looks like rubber in photos) and this is what I would call 'active' protection, compared to the passive protection on the Otterbox. What I mean is that the Commuter is more likely to slip out of the hand, but be better against drops, and the Tough case is less likely to slip out of your hands, but make be less effective against drops. Also with the Tough case having rubber all the way around on the front, it's rock solid when sitting face down on a table surface and less likely to be knocked off.

Also, if you like to change your case on a fairly regular basis, the Otterbox is not an easy case to remove. Not that difficult, but the Tough is about 3x easier. This is a big deal for me, and combined with the nice secure feel, the Case Mate Tough is the preferred case for me as a daily wearer. If there are days where I feel I may need some extra protection against, say rain, I may be a little more inclined to throw on the Otterbox Commuter.

Either way you can't go wrong as both are great cases.
