Tube vs Picture Video Sharing Site?

Hi. I need to know which is the more sensible to make more $ for adult sites. Tube site or pics and video download site? I know tube sites except the biggest ones sharing the videos with embed code but this way is not effective I think. Right? Cause we can't add the ads infront of the videos and when the user click to screen then redirected to original site. So, I should hosting the videos in my own server. I confused! What is your suggestions please? Could you help me about this topic? Thanks.
