In green grass, the Sukhoi wasn't even able to take off, sure the dried grass helps, but I've flown in compacted ground and asphalt and that is sooooooooooooo much easier. So no, not better than hard runway in any sense. Bumps and friction gets in the way of speed and besides the plane suffers a lot of stress. The dried grass compared to asphalt and alike is not a better but a very, very, worst.
If you can't take off easily on an asphalt runway you gotta be doing something very wrong
