Killer's Blade: Diseased dmg(can proc defile), cheapest cost, Assassination skill line passives, single target, 300%+ dmg on 25% or under hp, Can be used with any weapons equipped, heals you if target dies.
Executioner: Sucks for the low increase to dmg. Pick reverse slice.
Reverse Slice: Physical dmg, avg cost, deals 65% of the full dmg you deal as aoe to close targets in a small radius, 300%+ dmg based on missing hp from 0-50%. It's dmg increase is gradual so more useful if your target is 25-40% range by offering more dmg in case you cast it too early, but weaker dmg if you cast it in the 10-25% range because you will only get the full 300% dmg if the target is next to dead anyway. Requires you to wield a 2h.
Steel Tornado: Same execute mechanics for dmg as reverse slice, 9m aoe range (way better), expensive cost, more dmg because DW weapons can have higher weapon dmg. Innate +20% extra execute dmg under 25% hp from DW passives (closes gap with Killer's Blade), +15% dmg to targets under CC.
So IMO option 6: STEEL TORNADO
