A more subtle difference (or more obvious, depending on your perspective) is that IFLs always run at full speed on machines like MP3000 and z800 that support "hardware capped" CPs. I guess this still applies to z890 too... So if you have a 7060-H30, or a 2066-0A1, if you get an IFL it will run at "normal" speed and not at the speed of the CP.
