Depends. Some people (such as jinx or draven) really want to secure kills, whether it's for more gold, increase in teamfight power or whatever, and they should probably take Coup De Grace. For many ADCs, this is a good way to hurt tanks, Black Cleaver/Dead Man's assassins, Caster supports who build redemption (a lot of supports).

If you think about it, if you are 100-zeroing someone, Coup De Grace gives a 7% increase to 40% of your damage, (that damage would have normally been ~37.28% of their health) so it would take raw damage equivalant to about 97% of their effective health

With minimal buff from this (4%) it takes 96.15% of their effective health to solo them from 100%,

From that, as long as you have 150 less HP than targets, and you are the only one dealing damage, this is more effective. Once other people start doing damage, the effectiveness drops, but that's at minimal levels. From max % increase, 12% increase to damage, it takes 89.28% of their effective health to kill them, and does more damage when they are below 40% than Coup De Grace does.

I could do the math to figure out the health threshhold for each tier of health difference where you doing all the damage makes this strictly better than Coup De Grace, but I'm lazy and about to get in queue. Might do it later, sounds interesting.

All this math assumes any healing/shielding below 40% HP has the same amount of heals/shields above 40% (ie, 40% of damage is dealt below 40% of health, and 60% of damage is dealt above 40% Health)

TLDR: If you do 100-0, you'll always get slightly more damage out of Cut Down as long as they have at least 150 more HP than you and don't heal/shield excessively below 40% max HP. I think it would be reasonable to take this over Coup De Grace, especially when you can switch it last second after seeing their team.

Note: Is there any difference between Coup De Grace and Last Stand wording it as Deals x% Increased Damage and Cut Down wording it as % Bonus Damage? Or is that meaningless and only something I would notice

Note 2: does this scale linearly or does the damage step as shown in the mouse-over? because that seems like a weird increments to step the damage up at.
