Rust or ARK?

Okay so both of these games look really good but I can only get one of them and I can't decide which one to get. If you have either game it would help to know the good and the bad of both. They both seem somewhat similar sort of in game play. I just can't decide...

Buy rust its better by personal use, ark si good but it harder and you get raided FAST well it depends on server, but i thin you should get rust its more fun wioth firneds

ark fo sure million times better
