I'm pretty much in the same realm as the rest of the opinions here...
VOTC Leia's a place-holder at best. She could be improved, a LOT, and so that's one I'd like to see them redo. The Medical Frigate Leia from Legacy improved on the body a little bit, at least the articulation, but not a lot. ANH is a figure that could use a ground-up resculpt though I believe.
I can't say I'd change the scale though... Leia's tiny, so the figure's tiny. It works out. I wouldn't change that.
