Really depends what your operating to/from. I used to own a share in a TB9
but now fly a C182RG and a friend has a TB20.
We are both regular visitors to a few of the Scottish islands with relatively short runways. We have no issues with runway length whereas the TB20 needs to keep a watch on its weight and some strips are out of the question.
I understand the TB cruises slightly faster than the 182 but burns more fuel too. I have also heard that the TB rides the bumps much better making it a good IFR platform.
You've also got a great support network through the TB Users Group/Forum. Lots of active UK and European members and annual Eurpean get togethers. Cant say the same for the Cessna Pilots Association which is pretty US centric.
