Last I heard Primal Groudon and Xerneas were pretty big. My information is quite dated however.

Primal Groudon was the most popular Pokemon in Ubers as of March 2016.

Here is a link that a helpful person gave me on Showdown. This will show you all the 'top' Uber Pokemon

It appears that you were correct sumwun, Primal Groudon is the most used Ubers at this point in time
