If we leave out "healthy," sure they're an alternative for some who leave JWs. There are some whose only complaint is that they can't entertain the heavenly hope without being considered odd balls in the JWs. Some may have read the older literature and think of Russell's time as being like a golden age.
But beware! Russell had some loose strings in his teachings which the Bible Students have never cleared up. In fact, that's why Rutherford had to start making changes, as any succeeding president would have had to do no matter who he was. A Bible Student, then, must live with a certain degree of ambiguity. They don't always agree among themselves, and frictions can arise which are prevented in the more authoritarian WT.
I think, in many respects, it is more difficult for a JW to be re-educated as a Bible Student than someone coming from Christendon, because the two religions are thought to be alike when in many ways they have diverged. Someone who doesn't like self-sacrifice shouldn't attempt it, for it is believed that in order to enter the race for the heavenly kingdom one must make a "covenant of sacrifice" - agreeing not to live a "normal" human life, in exchange for the heavenly life to come. Russell once stated that it's OK for someone not consecrated (or "dedicated") to spend money on strawberries (a delicacy in his day), but the consecrated ones should think twice, as their money is better spent in the Lord's work. So the self-sacrifice is there, but it's not supervised by an organization. In fact, the WT has tricked the Witnesses into living a consecrated life without the heavenly reward in view.
On the positive side, while we frown on 'following a man,' there is something to be said about having a personal saint (such as "the Pastor") as opposed to an impersonal organization. It may be an idealized image of the man, but it is someone who has gone before us and supposedly won the prize. Sort of like Paul - "Be ye followers of me, even as I also am of Christ." (1 Cor. 11:1) As I said, what is an alternative for some is not an alterative for many.
