For an edge case like that where everything is at the top, then even stock find-file is fast. But then, your current directory contains many files then you may one to look around to see the files in that directory. In that case, Ido cannot do it because you cannot have an actually buffer to scroll up/down to see. In this case, with Ido, you have to drop into Dired, look around and start ido-find-file again.

helm-projectile is really nice but if you want to look at the current directory or navigate around, you should use helm-find-files. C-j means that you proceed to the next level, that is either a file or a directory. Hit 1 means pressing one time. Hit 2 means pressing 2 times; pres you hit C-j twices and if your highlighting is on a file, then the file content is opened up in another buffer. You can also press C-u in helm-find-files; its has the same effect as pressing C-j twice. You can navigate the other buffer with M-<next>/M-<prior>.

Actually, navigating back and forth with C-j/C-l is much faster than <tab> and <delete>/<return> since both of those keys are on the home row.
