I have to say that both aircraft are absolutely fantastic... I hesitated buying any of realair aircraft, and that was a big mistake. I bought the SF260 and then the B60, after that I did not even hesitate to buy the Turbine.
Even then the B60 was one of the more immersive experiences I have ever had in FS. The tubine as well, to an even greater degree.
I have this to say about them both. . The B60 is like an old loud muscle car.. and the turbine is like a newer supercar.. Both are fantastic in their own right. I would not hesitate in buying either one.. or even both... they are works of art, and work quite flawlessly.
