The only players that offer some information about the video are: Soapbox, MyHeavy and Vimeo, while MyHeavy lets you rate the video from the player. If we look at the video quality, Soapbox and YouTube seem to be the best and also the fastest. Revver is the only service that shows ads at the end of the video and does a revenue split with the publisher. The easiest to share are the videos from Soapbox, MyHeavy and Vimeo, that lets you copy the code directly from the player. Google Video only wins at simplicity and design.
That means Microsoft's Soapbox has the best video player. For the moment, Soapbox is an invitation-only service.
