I played Oakmont on a hot July afternoon post tree removal and came to this conclusion:
Oakmont is a masterpiece.
I have defended its rightful place as an equal to Pebble with regard to the ongoing Huckaby-Pazin debate (which must seem incredible to my good friend Mr. Huckaby) but Oakmont is that good and better in some respects. I wouldn't be able to pick between the two as to which is "greater." Heck, like everyone else I'm in love with Merion - the Scarlet Johanson, sexiest of all golf courses - and wouldn't be able to pick between it and formidable Oakmont.
I've also played Winged Foot every Anderson Sunday for seven years, not as a competitor as Mucci and others would quickly surmise, but as a guest with Southside in hand.
Believe it or not the Open left ALOT of gas in the tank with regard to greens set up and speed compared to Anderson Sunday at WF and normal everyday set up for member play as well. The pins are tougher for the membership and MUCH tougher for the Anderson than they were for the Open.
All things considered, over the course of 72 holes of Open play, (IMHO) WF would yield a higher winning score than Oakmont everytime. Over the course of 72 holes of the toughest realistically playable set ups for each course, which, again, incredibly MAY not be an Open set up, Winged Foot I believe becomes exponentially harder.
Therefore, Oakmont will NOT play as tough as WF.
Furthermore, for those who haven't played the courses, for everyday play sans Open rough, playing either course is a most enjoyable exercise and not the drudgery that one might presume from TV viewing during a US Open.
