I use a HTC one M8 as my works phone, really impressed with the cleanness of the skin to Android HTC have used on it, battery life, look and feel are brilliant, only downside is that the camera is probably best termed average in daylight but works OK in darker conditions.
For my personal phone I have a Galaxy Note 3 and I’m not too bothered with Samsung’s skin vs HTC, the battery life is better still as is the camera, downside it doesn’t have the great look and feel of the HTC.
