Used free for a while but bought this and happy with it.

I had been using the free version from their site for many years pre macOS 10.11 and was alway happy with what it would do. I recently had a rather large (1GB+) zip file that Apples built in utility, Archive Utility, would not handle correctly. I purchased Keka 1.0.4 from the store and it handled uncompressing the file with out issue.

I have not yet upgraded to 10.12, and will be waiting a few more months before doing that, so I can not attest to any possible 10.12 bug issues noted in other reviews.
