Komodo, hands down. The technology is better. The solutions are better. The community is better.

Komodo allows many new chains to spawn. Pirate just spawned (the z only block chain). KMDice just spawned (dice smartcontract chain). Steaming video chains are being researched.

Komodo has smart contracts called crypto conditions. These are the first ever implementation of utxo based "smart contracts"

Lots and lots more
