While I don't think any type of corner is 100% foolproof, I have had great success with what I term, "The Shutdown Corner".
There is a difference between the cover cover corner and the shutdown corner in that the cover corner is more created in an effort to chuck you at the LOS, release and then run with you. It invites you to throw into coverages. The corners are very strong as well and will man-up on a receiver.
The shutdown corner was created to be the most physical player on the team. For 60 minutes, he is put on an island against regular athletes and athlestes with arrow bases.
He is the anchor (along with the RLB and DT) of our defensive schemes. Yes, every once in a while, under speed time clocks, you may mis an assignment but for the most part, if you place the player in the right spot, he will defintely handle up on his business.
Take a look at this Youtube footage of one of my "Shutdown Corners".
