ARK aberration creatures

Southwest has the most, but it's the biggest and most mazelike of the zones, so it takes a little bit to learn the area. It's easier if you start from the Fertile entrance in my experience. Also be careful that the border walls are a little tricky there.

I'm wondering which surface area on abb is the best for getting drops with high quality loot or a high quantity of drops at the same time. I have a drake to do them so difficulty isn't an issue.
