It's true that vim probably contains all of the functionality of tere, but IME browsing with vim is still a bit more cumbersome (and I'm not sure if you can configure it to print the cwd on exit, though probably you can). The extra '/' keystroke in each subdirectory for type to search, and the auto-cd really does make tere feel smoother.
Also netrw is a bit of a mess; I once found a bug and thought "I'll write a patch". After five minutes of browsing through the code ([insert Eddie Murphy meme]): "yeah, never mind".
