At the same time steemit is just a website. There are many other clients to interface the steem blockchain such as steempeak, busy and others.
What's important to distinguish here is the technology behind them. As @bitsignal mentioned, Lit is based on Ethereum, which at the time is having scaling issues. When Ethereum implements casper and it scales properly then we will see more interesting dapps on it.
Otherwise steem is the way to go! Waiting for an upgraded version on eosio :)
But steemit user very cheap to give a vote.... Lit is different, all user easily give a vote
