Versatile isn't always the number of sets it can run, but generally how easily you can fit it into a team and how much support you need to give it. In my experiences using Garchomp (both during this test or pre-banning or in DW), Chomp is definitely one of the most versatile Pokemon in the game, being able to fit into pretty much every team you want it to and it would still do what it does.
