OK. So, if you want to have the influence and increase voting power, then just go ahead and buy the STEEM Power. You'll save a step. But really, you can do it either way. I don't think there's any distinct advantage or benefit to buying one over the other.
You may want to wait and see what happens with tomorrow's hard fork though. Things will be changing, particularly influence.
True.
Thank you so much for your precious advice @ats-david
