There is "no smart move" to move to EOS blockchain. In blockchain there are trade offs in platform use, trade offs like true decentralization, security, scale-ability among many others.

Ethereum is a clear definition of decentralization. Also, there have been several changes and improvement going on from the developers and as software's continues to improve there would be a smooth transition from PoW TO PoS and becomes scale-able. EOS is relatively new and will need time to house as many dapp that is currently sitting on the ethereum blockchain.
