Radium [RADS] will implement Smart contracts based on nStratis protocol next year and sitting @ mcap $18m and cur price 5$ having ONLY 3.4m coins current supply.
The main benefit that's the core Radium protocol will be easily maintainable, as well as easily extensible and auditable by the expanding community of C# .NET developers. New features which do not require integration into the core network can be developed using smart contracts.
I am also a big fan (and investor) of Radium. They are technically advanced and I appreciate that developers know very well where to steer the coin. Unfortunately, they lack marketing which would target simple investors (as for example me) without knowing all the technical background.
