AFAIK the navigation stack is much more popular in the community than the nav2d stack, giving a major benefit for someone who's getting started, since there are more questions asked and answered about it here and more tutorials available on the wiki (and other places).
This does not mean that the navigation stack would be the best solution for a problem you're trying to solve, but when learning I would always choose the most popular option.
