Steem and Ether are both eyeing smart contracts, and are facing many competitors. (EOS, Tron, Neo, Lisk etc.). But both have strong sides, both have a lot of working dApps and are some years ahead of others.

Lisk i dont think has any dapps people use, EOS, TRON and ETH have extremely low traffic on any of their dapps.
The top 3 dapps on Eos, Tron and Eth combined get less then 1/3 traffic of Steemit.

Its basically all hype, bot bet transactions and uninformed investors that keep those 3 on top of the food-chain. It cant last.
