It is hardly a surprise that Greg Pak self confessed Hulk fan boy thinks Hulk could beat Superman since he thinks the Hulk can beat just about anyone.
My guess is amongst most writers old and past who are neutral on subject would beg to differ.
The fact is if you are talking about either an average version of Hulk over the years v an Average Superman i would say Man of Steel has the edge and if you are taking the most powerful versions say WB Hulk v pre crisis Superman then Supes still takes it.
The most obvious factor is as well as both being extremely close in strength Superman has literally a host of other powers at his disposal and most importantly Super speed, honestly if written properly the Hulk should hardly be able to land a decent hit on him Whilst Superman would be able to pick the Hulk off dozens of times a second.
Also if he really wanted to he could just keep fight at long range.
ONLY way Hulk takes this would be that Supes just fought as he did DD, and even then, had a decent shot to still win it!
