I will go for bitcoin cash and ethereum.

Bitcoin cash is a bitcoin classic hard fork which improves the speed it takes to confirm a transaction. Bitcoin cash also has increasing supporters and though it is not as decentralized as bitcoin, it has less dictatorship. Just like bitcoin classic it has supply limit of 21 million.

Ethereum is innovative and I believe it's smart contract concept and very supportive team will make it last long. It might even surpass bitcoin in market cap.
