I'm confused. I was thinking in terms of Steem and SBD, not USD. So if my goal is to increase maximize my Steem, I thought the calculation would be:

• SBD > Steem : take 100% SBD payout option
• Steem > SBD: take 100% SP powerup

What I'm not sure about is if the reward payout is different for SBD vs Steem, which is important to know.
