Well if you ask me I'd go with steemit. Weku is still very new, it's essentially just 2-3 months old and it's still in its infancy. Let's ignore the fact that like whaleshares.io they completely copied the steemit user interface, Weku is still full of bugs and when you receive a pay out, it still says SP(steem power) instead of WP(weku power). Moreover, Weku coin or Weku dollar hasn't even been listed on any market yet so as of now the coin doesn't have any realistic value.

I'm sure it'll be something promising in the future but as of now steemit is the better option.
