The paid version of Tailwind does have some great analytics available to you, including a few things that I haven't figured out how to find with Chrome — at least not easily. (Here's my affiliate link, if you'd like to try Tailwind for FREE with no time limit, up to 100 scheduled pins!)
However, there are also a few things that can't be found in Tailwind that CAN be found with these hacks, including the total aggregate number of repins for one of your pin images (even the stats you see above one of your pins on Pinterest only show up to 90 days in the past), or any stats on OTHER people's pins, not pinned to your own account.
I personally use and love Tailwind myself, and I still use these Chrome hacks all the time!
