In Chinese media we say WZ10 is comparable to AH64D, not better. In some aspect AH64D is stronger, e.g. the takeoff weight. However, WZ10 have also some strong points, e.g. hilicopter combat.
In the video WZ10 is compared with AH1Z and Mi35. Both of them are first generation attack hilicopters, Mi35 can be count as 1.5 generation. WZ10 has the newest design, it is the second generation attack hilicopters. Compared to AH1Z, WZ10 has advantage in the takeof weight, power, armor, weapon and the potential of upgrading. Compared to Mi35, WZ10 has better mobility, design and electric equipments. Another point is that Inida knows almost everything about Mi35.
T129 is not introduced. Maybe T129 is not in the competition.
