In my opinion each and every platform have specific differentiation. Still I have test few one like as Ethereum, NEM and Stellar. Ethereum is not bad but everyone is going with Ethereum according to there business needs, but still few other platforms are also good. Waves is also promising platform. But I prefer stellar platform. As I seen just few ICO's were conducted with Stellar.

Rather I would prefer choose related platform according to business needs. Blockchain have bring real revolution in various industries and businesses
