AFAIK, meta-webkit is the one you should be using. Its the one currently 
being actively maintained by the WPEWebKit folks.

I've used Cog before. Calling it a "brower" is generous.... it doesn't 
have any of the normal browers trappings like history, navigation (e.g. 
back button, refresh), tabs, etc. It's probably more accurately 
described as an HTML5 rendering application, which sounds like all you 
really want anyway.

FWIW, I've always been under the assumption that GLES was required for 
WPEWebKit.
