Ok, so i'm getting blender, is that the best for this or is it not good for beginners?
Milkshape is generally more user-friendly, but it does have fewer options than in Blender. However, rendering and exporting things with Blender is sometimes a huge hassle, while Milkshape's render and exportation process is pretty easy and generally bug-free.
It ultimately depends what you want to model for.
