At the end of the day, someone will come here to show you how EOS will be big, that it was created buy the creator of Bitshares and Steem etc....another one will come here to say that ADA will be huge because they want to implement a secure PoS algorithm, sidechains etc...
In my humble opinion only you can make this decision by reading whitepapers and documentatios carefully, research the team, the idea, the potential, it will take several hours but it's your best option
