I don't think you can really give a good comparison between the two.
Dragon Talon has the very clear advantage speed-wise, so for purpose of delivering quick crushing blows they are far superior. The disadvantage is that you need a more skill points to hit a good number of kicks and the last few hits are dependent largely on the boots and the str/dex of the assassin. Also you need to go close to the enemies to deal the damage, which can be very dangerous in hell.
Blade Fury on the other hand has a slow rate of crushing blow but needs only 2 points to reach its full potential, leaving a lot more points to spend between trap synergies. This goes well with the fact that it is ranged and you can focus more on laying traps and then spraying out the blades while the traps dish the damage. With greater synergies, the traps will be more significant in dealing the last few hits.
I see them as two rather distinctive styles of play but personally, I prefer the blade fury route as it allows me to have better traps which gives a better balance between physical (from ethereal weapon or crushing blow) and elemental (high trap synergies) damage. In a way you also can call it a safer route as you would not be in full combat with the very heavy hitters in hell and can have more points to spend in vitality or even energy.
