Selling Your Votes To Voting Bots Comparison - Who Is The Best?

I did a default configuration, when my voting power is 90+% - I sell my votes.
I do this because of course I can do some extra money when I don't have time to be active, and my Steem Power just sitting there.
So I just wanted to share - how much they pay, and does it worth it?

Well I tried two services
The first is @minnowbooster
https://www.minnowbooster.net/
And the second is @smartsteem
https://smartsteem.com/

So lets start with @minnowbooster
It is not latest statistics, because I didn't sold my votes for some time there

I think I can say it earns 50% the $ amount I give, and there is also curration that will be 20% of whole.
So for example I gave 0.39$ vote, received 0.17$ later I will get also 0.39*0.2=0.078$
Which in total means that for 0.39$ vote I will get 0.248$ which is 63.5% of what I gave

Now lets see @smartsteem

Lets calculate I did vote worth 0.896$ and got for it 0.21$, + curration(0.1792) it is 0.3892$.
It is 43%

Bottom Line
My conclusion thus is that @minnowbooster pays more, 63.5% vs 43%
It worth mentioning that the Steem numbers are a bit broken, and if it writes 0.896$ it doesn't mean that you will get this amount(it now pays about 80% SBD and 20% SP).
But for comparison, it is easy to see for whom make more sense to sell your votes...
