Dense Point Generation - setting differences

[82Curls]

Hi all,

I've searched the forum on this, but haven't found the answer I'm looking for.

I use Agisoft to create both rectifies plans and elevations of buildings and 3D models of the subjects (which I host on Sketchfab).

With regard to dense pc generation; is there going to be a vast difference in the quality of both my ortho and 3D model if I choose between the low - v high options?

Also, what effect will the aggressive vs other options have please?

Thanks in advance.
