Difference between BetterTouchTool (BTT) and BetterSnapTool (BST)

I bought a licence to BTT when I first got my MacBook Pro a few years ago never really did much with it but I liked the idea if I wanted to customize my Touch Bar and more I could.

Then I went and bough a 49'' Dell monitor and found BST and bought a licence to that product to use its custom snap tool, not realizing that it was available in BTT also.

Either way I don't mind paying for both tools and supporting these projects. I was just wondering if there was a list somewhere of the differences between the two apps. What is available in BST that is not available in BTT?

Thanks again for great products and I look forward in future features.

BTT has it all, BST is for snapping windows about.
