Hi
There are some other flavours , and even within one flavour the actual behaviour will depend on the design.
If you want to know all variables that make up a compressor you could try DMG Audio's compassion, you can use them in demo mode for a while.
Don't forget to download (and read ;-) the manual.
In expert mode you can design your own compression behaviour, and in the manual a lot is explained about the history and differences in design parameters.

Compassion has a graphical history view so you can see what/how it compresses (up to a certain extend)

Enjoy, Daniel
