Because Deaths Dance helps against burst which is favourable for Kog'Maw, since he needs to keep in the fray for a longer time. His DPS will help sustain him trough burst.

Gunblade would indeed be favourable if the enemy has a bunch of tanks without any assassins. But in that case I'd probably take BotRK over gunblade for the passive.
