Generally drag and drop works less well with LR on Windows, and generally I would agree with you that it's not satisfactory.
I'm not totally in agreement though. If you drag and drop into InDesign, you're dragging the full size image into InDesign and then relying on its resizing. For image quality, you're probably better off doing the resizing in LR / PS where you can apply the right level of sharpening.
