ETH, It doesnt have the problems associated with Bitcoin. Its developer team is more active than Bitcoin.
Above all, the number of projects being launched on ETH blockchain are humongous. THe sheer number of smart contract being made on Eth, justifies its price and usage unlike bitcoin which is called just a store of wealth (which get replaced by something else if they dont improve their tech)
ETH is not without issues, but at least their dev are making constant and visible efforts to mend it.
