This is only my opinion.
I think placement of views is easier with Drawing
wf> I don't follow this one. How is entering X,Y coords, then modifying them if the scale changes easier than "drag and drop"?

With DD, I can place the lines of axes and change their appearance, and a line arrow for the text
wf> clear win for DD. TD has view centerlines, but their appearance is fixed. Still no proper leader and note in TD.

on the other hand, I do not know how to modify the appearance of the hidden lines in the 2 cases
wf> I don't know how to do it in Drawing, but in TD there are preferences for line style and color of hidden lines

With DD we can add the tolerances = / - on the dimensions
wf> TD also.

In the 2 systems we can not change the numerical value of the dimensions, nor the symbols like the signs of diameter, Rays nor degree of angle
there is also no option to delete the decimal zero
wf> in TD, the is the job of the FormatSpec and Arbitrary properties. See picture above.

This is not an exhaustive list
in attachment: the same drawing presented with the 2 systems
wf> I found only a TD drawing.

wf> I noticed you are using the "Coarse View" option. This is great for speed during model development, but for finished drawings it causes lots of short edges and extra vertexes from the polygon approximation.

Thanks for the comments.
