Upsampling vs Drizzling

If you're developing information from a telescope and camera that were perfectly sampled for the seeing conditions, wouldn't it be better to upsample than drizzle? I was recently posed this question by a viewer, and it's a good question. In this video, we'll process a tough DSO, the Ghost Nebula, with well sampled information and see whether upsampling or drizzling produces a better result.
