What's the difference between Bronto and Diplo?

Maybe they are relatives, but I prefer Diplo to travel for materials, only it is more difficult to do because of the many distractions from predatory Dinos like raptors, it Is a problem for small players below level 50 who still struggles against some types of Dino, although Diplo doesn't have attack damage but it's quite useful for traveling Short term to long term, Diplo has 10 extra seats on its saddle which can make it easier for all your friends to travel with you, around the island And beat Giga together, while about the bronto I'm still not too sure because I haven't opened the saddle yet
