Phil77, with all due respect, but if you don't even bother to read available information on the subject (ie. the article) you are in the wrong topic in my opinion.
Go have a look, the article definitely sheds some light on the issue, of course it might be biased or not or not provide the answer after all, but Tim Tucker with his 18,000+ flight hours has been around for 40 years or so and flew from small to big and from turbine to piston everything. He was around when I was not even born and whatever he says can't be completely dismissed.
The article is also not asking you to stop believing turbines are more reliable, so it doesn't matter reading it I promise.
I am not on either side by the way, I am from a Robinson training environment but I wouldn't mind flying turbines and I certainly hope that both keep my blades spinning.
