The press conference was certainly lively, no love lost between these two. Khan is quicker, Brook has better timing. Brook has more power, Khan has the weaker chin. Brook by KO, it'll only be a matter of time imo before he lands one and it's lights out again.
Khan seems to relish the fact he's fought so many world class fighters - he's been knocked out cold but he sees this as some sort of achievement and I think Brook was right, he's avoided this fight because if he fought Brook years ago and lost, the bubble suddenly bursts, the pantomime is over. It was easier and more financially beneficial to continue fighting foreign fighters in exciting fights that people always tuned in to watch because you couldn't blink, his blistering hand speed meant he'd dominate certain opposition yet at the same time his complete lack of ring IQ and poor defence meant he could be KO'd at any moment. Khan excelled in certain areas but was very poor in others, that's why he had such great highs and devastating lows, meanwhile Brook was more well rounded as an overall fighter and consistent - you'd never see Brook getting knocked out cold by a Breidis Prescott for example.
Definitely Brook by KO for me even though he's probably a shadow of his former self these days.
