The ICO was great. Token sale was successful and the the quota was reached. However, the potential of the coin and its possibilities does not depend that much on its ICO. Too much hype during the ICO but look at ETN at the market right now, it still hasn't shown what people thought was so great about it. Maybe they've thought too highly of this coin.

Anyway, there's no such thing as best ICO. There are only good advertisers, a good team to back the project and great investors willing to trust and support the project thru investing. With these, any ICO can be successful.
