Voted for Steem Power ( Mine forever).

With Steem Power Delegation (90 Days), you lose everything, except the curation rewards.
But for 200 Steem Power, the curation rewards will hardly be 11 Steem Power for 90 days.
Let's say you earn 0.01 Steem curation reward per upvote.
You upvote 10 posts per day. That is 0.10 Steem per day, which is 9 Steem per 90 days.
But you probably won't earn 0.10 Steem curation rewards daily with 200 Steem Power.
Nowadays I have around 170-175 Steem Power, and I earn around 0.01-0.07 Steem Power per day as curation rewards.
So choosing the 90 days Steem Power delegation is not profitable in this case.
