I've used transcribe! for years, is a great tool. Decoda has interesting features, but also misses some (to me) essential functionalities: tempo and time signature changes, slash chords suppoet, manual editing for bars, copy and paste chords/sections, etc.
I contacted zplane about this, and they said to me that they plan to implement some of these features in v2.
