I could not see where Open Camera is significantly better than the other camera apps I have installed (the stock one  CameraNextMod  Google Camera  etc. plus those from photo editing apps)  but neither could I see anything noticeably inferior with it. It is  however  the ONLY ONE with a widget that when tapped will quickly & automatically take a photo  adding a timestamp to it if you wish; and it worked well for me.
