Dear Arrakis not much and in this case this can be assumed like advantage ....
Could you be a little more specific?
Personally, I have to disagree. There are some major differences, starting in the engine department, when you compare to the old TV2s and quite a choice of avionics, comparing to the old "Ts". Larger doors, and on both sides, if you need it, etc..
A few things won't change, like crashworthiness, but - ce la vie.
If you ask my people Mi 8T is more pleasant to fly and much less vibrations
on cyclic.
More power, much more power comes at a cost.
