First of all, Congratulations on making this list, although I find a big part of it not that necessary, There is no need for 20 sportsbooks for a single user and the "real" tops being NitrogenSports and Cloudbet with a rising role for Sportsbet.io is enough.
Having a list is not bad after atleast people do have an option to choose among those sportsbook since we do have diffent taste on playing a certain site and also Directbet had closed its doors and shouldnt be on the list. You do have some point because people will usually go to the most reputable sportsbook and those ranking below those would not gain any attention for sure.
