>>109765526Bill and Ben are so great because of their downright brutal rivalry with the Troublesome Trucks. The trucks who to all other characters are generally the antagonists of the stories/episodes, but Bill and Ben don't take ANY fucking shit at all from the trucks and will literally destroy them without hesitation on a whim. Half the time out of their own enjoyment.
In fact, if I'm not mistaken, despite not being such main characters and thus getting less episodes (and thus less accidents), Bill and Ben have the highest troublesome truck kill count on the island. Either individually, or certainly together.
