I can't give you the difference in the controllers. But I do have the typhoon controller I got with my Steve's LED upgrade on my BioCube.
Here's what I know about the typhoon controller:
Mine has four independent channels
Each one can have its own start and stop time
Each one can have its own Ramp up and down time. If you set it for a 2-hour ramp, it will be 2 hours up and two hours down from the start and stop time.
each Channel you can set the minimum and maximum intensity. So if you had a blue Channel and wanted a Moonlight all night you can set a 2% minimum. I don't but it's possible.
The controller will retain its schedule through short periods of power loss. I ran a three day blackout once and had to reset everything.
It is connected to LEDs through a six or eight pin lead system. So you couldn't just plug an Outlet into it.
All in all, it gets the job done. If I knew then what I knew now I would have probably just got a better light system and pulled the lid of my Biocube. In fact we were just talking about doing that. I have a few extra xr30 Pros laying around.
Hopefully this helps you. Maybe somebody else has some info on the other controllers to compare.
