Using non-destructive modeling (or an “envelope” as I call if for the stuff I do) you can create any shape imaginable with a fraction of the vertices, this means changes can be done extremely easy and fast and you have total control over the polycount.

I “learned” about it watching Cédric Lepiller’s videos, I said “learned” because Cédric is a industrial design professional that uses a specialized set of add-ons he developed himself. But watching his videos gave me a good idea how to use Blender’s modifiers and even without his add-ons the fundamentals are the same, the rest was just practicing and experimenting.
