I have to admit, that is a fight id really like to see for they are both of collosal proportions (physically).
Unfortunately, comparing two completely unrelated characters from very different realities can be very hard and usually is impossible.
I for one, believe that broly would rape the living crap out of the hulk.
#1: I dont recall a time when the hulk could destroy a 'planet' in a mere 5-10 seconds with a single blast of energy or by simply just powering up (probably around 2-5 minutes of doing that will do the trick) (AKA adrenaline rush)
#2: I dont think Hulk has the power to transport himself many miles from his current location in an instant (very highspeed)
#3: If u think that endurance will be the downfall of Broly, you can think again once u have watched all three movies (the first one is quite enough)(not boasting 
)
for certain explanations made in and out of the movie say that the main advantage of being a legendary super saiyan is that you have unlimited power whatsoever. if Broly got tired all of a sudden from conjuring a chain of attacks, he would need only a fraction of a second to recover then continue. However due to Broly’s unstable mentality (retardedness, lol) caused by his hatred of Goku, Broly just simply attacks like a berserker, not waiting or having the patience to use a specific strategy.
4#: Hulk does not have any of that except that he attacks like a berserker aswell (most of the time anyway)
Therefore i conclude that The hulk has no chance whatsoever of defeating Broly
unless he somehow attained the same powers and attributes as Broly or steals those powers off of Broly. i could ramble on all day about the ways that Broly can simply annihilate The Hulk if wanted to. nevertheless Id still like to see that fight ^^
