Voted for Other.

I have used MinnowBooster in the past a lot. To sell my vote and to earn Steem Dollars (SBD) daily from them by delegating Steem Power to them. I rarely used MinnowBooster to upvote my own posts.

Sometimes I use Steemvoter to set automatic curation for my Steemit account, when I don't have the time to manually curate (upvote) contents, but nowadays I am curating (upvoting) posts and comments manually.

Nowadays I am not using paid upvote bots, but I am using free upvote bots.

I am now copy-pasting a part of my own reply from Musing.io with a little modification, because it is related:
Yes, free upvote bots are exist!

For example the Minnow Support Project. Free upvote service. See the Peace, Abundance, Liberty Discord channel (https://discord.gg/HYj4yvw) for more information.

Another thing: If you use Busy.org to post and you use the "busy" tag on your post, you will automatically get an upvote from them. I think it is 1 upvote per day per account. The value of the upvote is depending on how Steem Power your followers have. The more Steem Power they have, the more value you will receive with the upvote of Busy.org.

One more thing: If you vote @steemhq.witness for witness, they will send you some Steem monthly. They (@steemhq) will also upvote at least one of your posts weekly.
