Well, I have the C-3s smaller brother, the C-1s.
I have comparded then to Totem's and Missions and I have heard a few others from Paradigm and warfdale.
The Totem's sounded better, but they cost 3 times as much.
Mites
Its hard for me to recall my feelings compared to others I have heard, as it was a long time ago. I know the missions sounded a little forward while flipping back and forth between the 2.
The warfdales had a weird sound to them(my friend has these). They were not bright, but they lacked ANY detail, and the bass response sucked.
The paradigms had great mights and treble, but they also lacked in the bass department.
Hope this helps,
