The Isle Legacy is currently the best version to play on due to its high number of dinosaurs and activity. Legacy is the original build and was what kickstarted the "dinosaur survival game" genre. Legacy includes many mechanics such as nesting, groups, a chat system, sandbox, and many other features. Legacy also includes many dinosaurs (some are currently unplayable and are only available on certain sandbox servers). Legacy also includes many, many secrets to be found by you! Such as the mysterious creatures who stalk the night or the mystery of how the dinosaurs got here. The Isle Legacy is a game I would highly recommend to people who like survival games, dinosaurs, or who just want to be the dinosaur.
