I'm not sure what points-system this ranking is using, but any list that puts Hinault behind Jalabert and Zabel is probably distributing the points in a disputable way -- e.g. giving too much weight to stage wins or placings as compared to overall wins.
I personally like to rank cyclists in a system of tiers. Top tier goes to all-rounders, and runs Merckx, Hinault, Coppi. Then there are separate tiers for stage-race specialists (Armstrong, Indurain, Anquetil) and classics specialists (Van Looy, De Vlaeminck).
