I think Silver Surfer would win, he's faster, and know show to use his speed, and his power cosmic blasts have a wide array of uses. Although I don't think it would be easy, he'd feel like hell in the morning.
silver surfer would NOT win. he has already admitted while fighting thor, that thor is more powerful. even when augmented by loki.... silver surfer just managed to barely over power thor. thor in warrior's madness has also knocked silver surfer out with a single blow. admitting you can be defeated... and being defeated.... hmmm silver surfer loses.
This one relys on the ''Lucky Hit'' technique where either SS or Thor will get one shot through the others defence while they're both completley knackered from the fight and knock the other out almost by accident. And since Surfer may be slightly faster than Thor he has the better chance.
hulk is strongest.. in the invincible iron man 6 hulk is shown to be stronger than thor and thing ....get this, COMBINED. he manages to close a valve to a gamma core that burned thing's and thor's hands.
i'm pretty sure that silver surfer could trump hulk with his cosmic powers. although i've seen surfer in harsh predicament that hulk would have had little trouble with.
anways if hulk>thor and silver surfer>hulk than silver surfer would win over the son of a god and very mighty Thor.
i would pick thor, basically coz he's been around longer so has more fight experience. but he would only win if he really used his head. on a head on fight id probably say surfer. thor with godforce owns ss tho.
