Is a marvelous designer needed?

Question

3D

Does it make sense to use marvelous designer?
Personally, I found the following minuses:
1) T-shirt, pants, jacket, etc. can be easily created with Extrude or a magnifier
2) No thickness, before dragging an item to Brush, you need to add thickness with Shell in Max or another 3D package
3) When importing, you need to scale and stretch on the character, even when setting sizes in the MD itself.

If you don’t make complex ball gowns, it’s better to use IMHO 3D packages (Zbrish, Mayu, Blender), I personally didn’t really understand the hype around this tool, if I’m wrong, then argue, maybe I’m not using it correctly.
