As far as I know there is no such list: the closest thing I know of is the raid kill board, and I think that just tells you "who killed Inny yesterday?" not "who has been killing the most raid targets over the past few months?"
However, if you're trying to decide which guild to join I highly recommend looking at the guild summary I made on the wiki, as it breaks down all the basic details for every guild on the server in to an easy-to-read table:
