That is the key - servicing. Second - frame age and condition. I agree with you, 100%, that if you compare the safety record and performance of a 40 year old Mi-8 which is not properly serviced with a new and well serviced French or US helo, I much rather fly in the latter. But that is a result of ageing and maintenance, not design. But take a Mi-8 and, say, a French Puma. Here is the Wikipedia data:

Though the two are roughly comparible, the Mi-8 is far better in terms of both the number of soldiers it can carry and in terms of armament.
Now take these two into some nasty environment (arctic, desert, tropical - you name it) and have them both operate without the support of a major maintenance facility. Which one would you pick?
I submit that there is a darn good reason why the Mi-8 is the most numerously produced helicopter ever and that reason is that it is a fantastic helicopter. at least for its time.
The comparison of the Mi-24 and the Apache would be even far, far worse for the Apache. At least the Puma is a good French helo, whereas the Apache is a typical American piece of over-engineered shit, IMHO.
Anyway give the Russian hardware a halfway decent maintenance and it will outperform most Western equivalents in terms of design, reliability and performance.
