What level of intelligence Superman should have is fully debatable, but personally I would be very happy to have a Superman who is very competent at what he does, very self-assured with a strong self-belief, and intuitive.
These are all what I like to see from the character, and to some extent Brian Bendis does show these traits in him, just not regularly enough. Oddly I thought Dan Jurgens had the balance right in his run on Action Comics three or four years ago, there was a subtle but definite attempt from Jurgens to tap and channel the self-assured and ever-resourceful Superman of the Pre-crisis years, a man capable taking charge of a crisis and using his combination of assurance, intuition, and tactical nous to deal with it.
On balance there has been a slight problem with Superman that goes back to the '86 revamp which removed him from any direct knowledge of life on Krypton, and made his intelligence and know-how purely earthly in its nature and limitations. Despite the various revisions over the years since he has never quite regained that knowledge and sense of extra wisdom that his Kryptonian heritage bestowed on him... he remains very much John Byrne's Earthly Child, when perhaps what people need today is the Unearthly Child we all looked up to in the Silver and Bronze-Age.
I much prefer him as shown in Chris reeves movies, as one having the accumulated wisdom and knowledge to actually use well his alien tech!
He was learning in his ship the accumulated knowledge of many worlds on trip to earth....
