What does Sellerboard for FBA have over STK?

Aren’t the two the same? Both provide profit and loss insights and indicate when to reorder stock, right?

Sellerboard is cheaper, I believe.

I prefer SellerToolKit’s user interface

I do think Sellerboard has some extra features that SellerToolKit doesn’t, such as tracking eBay profits.

Also Sellerboard has more in-depth PPC data compared to SellerToolKit.
