Alright, I just received the trident Perseus case, and I really like it. I've never owned the aegis, and I have only had the lg kickstand case to really compare it too. This is hands down better than any plastic case out there. All the cutouts are perfect on this case and I have not had any issues at all with usb or 3.5mm fitment. This case provides the most grip I've ever scene on any phone, on st. paddy's day I was wobbling and swaying around the streets but this phone was stuck to my hand, no drunk drops. You'd have to be in cardiac arrest for this phone to slip out of your hands. I never really like holding my handset up to my ear because it felt uncomfortable for long periods of time, but with this case on the comfort level is optimum for that talking stance. I think the only way to top this case would be for goodyear, michelin, or pirelli to develop a non slip rubber case for our phone (which ain't gonna happen).
As for protection, the four corners have the most protection, The front bottom lip is raised for a little front screen protection.. the top of the front screen protection is kinda of skimpy and the back is very firm on the top part. The different textures on the back is a nice touch for the grip on this phone and the side grips absolutely make this phone. If you know senior citizens with smartphones, you should recommend this case (Safe for ages 10 & up). Also, the speaker and mic cover are nice touches but I really don't run into many dust storms or work on a construction site so I can't comment on their effectiveness to block out any dust particles. It's definitely worth $12.99.
