Ido comes with Emacs, which is a big plus.  Flx can be installed from
marmalade repo.

Configuring ido for vertical output requires one line of code:

(setq ido-decorations (quote ("\n" "" "\n" "\n…" "[" "]" " [No match]"
" [Matched]" " [Not readable]" " [Too big]" " [Confirm]")))

I don’t select what file I want to open based on what color it has.
If I know what I’m looking for, I don’t need visual aides to find it.
If I don’t know what I’m looking for, I’ll open Dired.

> - Depends on what file type your highlighting candidate is, Helm opens it appropriately. For example, if you RET on a directory, Helm opens dired; if you RET on a file, Helm opens that file. You can also customize the application to open the files. Stock find-file at least can open directory; Ido simply can't.

C-d in Ido opens the currently selected directory.

If I want to work on multiple files at once, Dired does that for me.

Again, Dired helps me out here.

I’m not sure if this is actually true, but you can always use slash as
a path separator on Windows if Ido can’t handle backslash (which I
wouldn’t hold against it).

My overall feeling when I looked at Helm when this thread appeared was
that there’s already packages that do what Helm does that come with
Emacs: Dired, Ibuffer, and Ido.  Sure, Helm can interface with
Delicious, my web browser, and so on, and if that’s something you want
to do, then Helm is great, but for me, Helm is trying to sell me stuff
that I simply don’t need or want.
