In my opinion (and there will be others who differ) Tornado kicks the Ribtec's arse.
I have owned a Tornado myself (4.5) and bought quite a few for a business I used to run (4-5.5). In fact we had two of the older ones (mid eighties) re tubed by Barnett. I have also owned a Ribtec (4.75) and run several others (4.55-6.5).
Don't get me wrong there is nothing wrong with Ribtecs and in fact I was very happy with our old one but Tornado's of that vintage are in a different league
Can't really compare with Osprey as i don't have enough first hand/ownership experience.
That said you have to be very careful buying an engine of that age. Those 2 Stroke Yams were good engines, but 9 years is getting on a bit.
