They are both great, so I keep using both. There is a lot of overlap in terms of what they can do but they each have unique capabilities that the other can't do

They are both great, so I keep using both. There is a lot of overlap in terms of what they can do but they each have unique capabilities that the other can't do. I don't personally know all the differences. But for instance I use BTT to program my stream deck, while I use KM for my clipboard history because the built in GUI is polished.
