The Ecsta's are far out of league from the rest of the tires, and the V70 is just as far in the performance direction if it's a true "victor" series tire(50 UTQG). The Falken 615 is more DD than Autoxer in the autox category.
The Kumho XS is 180 UTQG but the sizes are not great. Shame, as it's good tire
