They both suck.
unemployment is at 5.4 percent! Take that Fox News!
Barack Obama just seems more reliable. Hillary is a very Machiavellian politician and has ties to Saudi Arabia. She's very duplicitous, likely to shake your hand then feed you to the dogs.
The longer that Obama is in office, the more gridlocked Congress will remain, which isnt necessarily the fault of Obama. Clinton may get around that, so I'd give her the nod for a first term more then an Obama third term
