Both definitely developed independently. There is definitely some crossover, but they have some different approaches, too. Both have trials. Both cheap enough that you don’t really have to choose.
And, as others have pointed out, they both use a standard OS X toolbar (like many apps, including Safari, Xcode, Mail, Keynote, Pages and many third party apps), as well as many other standard OS X controls and normal OS X-y things. That’s not bad at all!

I’m very glad they both exist.
