The size and capability vise, I believe Y-15 will be a success when it is cleared for exports.
It will come down to the total cost of ownwership of
a) procurement price
b) service life of the airframe
c) airframe maintenance requirements
d) engine lifespan
e) engine fuel efficiency
f) engine maintenance requirements.
Add all those together, for a comparison of how successful it will be. When it comes to transport aircraft, given how many flying hours they do, the cost of ownership and operations tends to be the most significant factor. That is why the C130 was so successful, it was cheap to operate.
Early days for the Y-15, and of course, China never seems to publish the data for items a) to f) so we never know the true data.
