Best I have found! new features often!

While sometimes not the prettiest (ssh Vs coda for example) it has more tools and references than anything I have come across. The fact that all the tools integrate makes it that much better. It feels like a unix tool set with a apple GUI to all the key features, if that makes sense? Totally worth every penny!
