It would be cool to see an evaluation of this against baseline. Software is a giant warehouse filled with soggy pinatas. Swing any kind of bat in there and you'll get some candy.
I'll try to do a blog on this specific aspect. It can be hard to apples to apples with other fuzzers and toolings but I can give it a try.
This tooling is specifically designed for "hard" targets, while "hard" is subjective, think targets with fewer than 2 CVEs a year. Where getting even a null deref is hard.
I have used this on some soft targets and it's just as if you ran AFL against it, candy everywhere. The upside is that this tool usually "finishes" in an hour (no more coverage, no more crashes). Making it a bit easier to develop mutators/generators as you can run them to completion faster and have a more effective development cycle.
