Planet wrecking is still planet wrecking... the amount of potential energy that will be liberated upon impact doesn't change whether it's one big chunk or a cloud of gravel... what varies is if it's released all in one place or spread out over half a hemisphere.
Either way, it's a bad day for the whole planet, you just get to die in a massive blast as the shockwave circles the globe.. or die in a planet-wide firestorm as the atmosphere is superheated by all the individual impacts.
Ironically... the former might be more survivable than the latter. If you're far enough away and in a deep enough bunker, the shockwave from a single blast might be dissipated enough to be survivable. The shot-gun scenario leaves you with an planetary atmosphere mostly devoid of oxygen and heated to a couple of hundred degrees celsius or more. It might not directly kill you at first depending upon construction of your bunker and reserves of 02 ... but you won't be leaving anytime soon.
