You are very right, H/T are of no use where you intend to use them. Following is just another user's observation, nothing more...
In A/Ts, I have done a similar exercise recently for my vehicle. I have used all the above-mentioned tires at different points in time except the H/Ts on an SUV ;-D. If you are already closing in to the budget of 20k/pc, you may consider Continental Conticross A/Ts as well. I got them at 19k from J. Rasheed, Neela Gumbad, Lahore replacing Dunlop Grandtreks. Conticross are a class apart.
The quality comparisons and user reviews are everywhere on the net.
Japanese Dunlops generally are lighter, quieter and last longer than Bridgestone with better cornering characteristics on road due to edge design. But are more like H/Ts in behaviour.
Yokohama is somewhat in the middle of these two and tends to be noisy at high speed. The slim grooves on the treads of tires you have short-listed, behave more like H/Ts rather than A/Ts when put thru demanding conditions.
