Also lifesteal applies to the physical damage dealt, not how much AD you have on your autos. This means that when you activate Kog's W, Cull is healing for 3 per auto twice as fast, while Doran's Blade is healing for (0.03 * 0.6 * AD). For that to be equal, you would need 167, or 100 when W is not active. You'll need to be level 16 on Kog'Maw for the Doran's Blade alone to match Cull, and that's only with W not active. It takes Kog'Maw 3 (~2.5) basic attacks, or 5 (~4.1) while W is active, to match Cull's healing at level 1.

Overall, especially on Kog'Maw, Cull is much better for sustain than Doran's Blade and of course earns much more gold.
