The configuration required with both is pretty somewhat rough for newbs.
Setup-wise it used to be the case that node was far more complicated, but luckily things are better these days.
I don't think the Ant is for more advanced users, to be honest both of them are pretty advanced. Ant is just for folks where Java is easily accessible and a node-based infrastucture wouldn't fly.
I think best might be to ease over the install instructions for the book and mostly talk about usage and featureset.
(And ideally we get better install docs for both ant and node BS's added to each project soon)
