When considering SongKong or Jaikoz I would say the key differences are:
SongKong
-SongKong also has a web interface so can be used on headless linux and nas devices
-SongKong only requires memory for the folders it is actually processing so does not use more memory for larger libraries and can therefore be used for libraries of any size
-SongKong has an Undo feature that can be used after files have been saved
-SongKong is simple to use with only a few main (but configurable) tasks.
Jaikoz
-Jaikoz looks like more like a regular tag editor
-Jaikoz is more flexible when matching with extra tasks such as Match to One MusicBrainz Album and Semi-automated match
-Jaikoz has much better manual editing than SongKong and alllows import of metadata from spreadsheet
-Jaikoz lets you check the results before saving
The most important feature that they both have in common is that you can point Fix Songs/Autocorrect to your whole collection and it will identify the songs and the correct albums whereas most other taggers applications only let you do this one album at a time
In summary SongKong is better for fully automated matching and can be used on more platforms, Jaikoz allows more customization, control and manual editing. For my own music collection by default I use SongKong, but use Jaikoz for situations that SongKong cannot resolve. Many customers have both applications.
