Well, there is a serious question of which Hillary it is that we're talking about. Historically, she's pretty easy to pull to the Right, but she's goddamned hard to move to the Left. Hillary is also, on paper, for universal healthcare; in the details, however, have always been remarkably less useful or helpful than one would like, and often by a wide mile. Hillary is also nominally for addressing "money in politics," but, again, the details matter. She's against "dark money in politics" --but she's totally for corporations and special interests financing the Democratic party and it's politicians in perpetuity. The Clinton's quite literally were the people who weened the Democratic party off of union money and onto the corporate tit, via the DLC. Anyways, details matter, and in the details, Sanders and Clinton are far, far apart.
That being said, Trump is a lunatic and an imbecile who race-baits, which is particularly devastating right now. So in the end, combined with the issues that she's conceded on, right now it's likely more advantageous to vote for Hillary while continuing with the Sanders' movement. Make no mistake, while I may end up voting for Hillary (so long as she continues to drift leftward), come November 5th, there's going to have to be a serious dialogue on the current state of the Democratic party.
