I'm not sure whether this is what i'd do in the states, but i'd vote for Clinton. She has experience and knows what the hell is happening to the United States.
Let me give you some perspective on Hillary Clinton.
During her tenure as first lady in the 90s, he espoused a message that "we need to get tough on crime" and "we need to increase mandatory minimums". You know, that sort of deal. Now, probably in a bid to make her sound better relative to Sanders' record on civil rights, has done a complete 180 fairly recently.
Her biggest doners include the likes of Chase Bank, Citigroup, Goldman Sachs, Morgan Stanley and Time Warner. Depending on the source you use, about 18% of her donors were "small donors", that is donors who contributed $200 or less at one time. Contrast this (again, depending on the source) about 75% of Bernie Sanders' donors being classified under the same definition of "small donors". This is, in fact, the highest by a gigantic margin of any of the candidates fielded by the Democratic or Republican Parties.
Related to her reliance on massive donations through super-PACs funded by large financial, defense and media institutions is the fact that most Americans polled found her "untrustworthy". I, admittedly agree, and am biased in this regard. But her email scandal relating to her time as Secretary of State has cast a negative light on her, the fact that she'd be the second Clinton to be president in the past two decades, joining the ranks of two (possibly three after 2016) Bushes. The American people are keenly aware and weary of the potential for entrenched political dynasties to take hold here. I mean, preventing political dynasties from forming in the first place is why we became our own nation.
Finally, you mention her "experience". I think you're confusing "experience" with name recognition. I'd argue that Sanders has as much if not more experience in several critical areas than Hillary Clinton, civil rights issues being one I already mentioned. Unlike Clinton, Sanders is keenly aware of the growing economic disparity between the rich and the poor not only in the United States, but globally. What's even better is that he's got plans to deal with this issue. So long story short, Clinton's got name recognition, but Sanders has the actual policy.
TL,DR: HILLARY "JET FUEL" CLINTON CANNOT MELT BERNIE "STEEL BEAMS" SANDERS
