Ninjapinner or tailwind??

Hi guys I started a pinterest account some days back.Its quite difficult to manage all social medias at a time so was considering for automation.Btw i came across ninjapinner and liked the pricing tag as its onetime payment and tailwind is on monthly basis.
Which one would you suggest for person who is just starting out and also has anyone tried these tools and what is their experience so far?
