Just to add to Beagles post the civi ones seem to have the roll sorted out but they still can be twitchie in pitch depending on the C of G.
Taxing you really need to use brakes,tiller and power coordinated to get it smooth. And then you have the different types of tiller one a star shape with a big arrow head sticking out or a handle type affair. If I was to brute force the steering on the star shapped one I would end up with RSI. Did one days worth of compass swing with one of them and I was in pain for a week afterwards.
And the Garretts are a bit of a pain to manage compared to a PT6 but are pretty good really considering the 25% fuel saving for having a direct shaft and they have a really high TBO. I have never heard anything good about the french engines.
And the AP's are still !!!!e. You just think its about to capture LOC then it runs out of servo trim and buggers off in the wrong direction usually decending rapidily approaching Vmo. Not that there are many AP machines out there I think only 20 were produced and they are heavy.
Keeps the day interesting though, not many aircraft out there though where you can cut your teeth flying everywhere manually IFR multi crew.
