    I personally find that fzf is better because I can 
    see where I'm going to end up before I accept the
    operation. 

I agree that's a must-have feature. Luckily z does it as well.

Type `z foo` and hit tab.

If there's a single match, "foo" will be expanded in place to the proper path.

If there are multiple matches, you can choose from a list of paths.

So, no mystery navigation (unless you want it) -- you can always see where you're going.
