I don’t think we can compare ant of them against the others as in my view they’re all different and playing with different team mates, etc.
I suppose if you put the question in terms of effectiveness rather than in qualitative terms, then the stats would provide a pointer. On that basis I think Hunt is still the man to beat. He had a great eye for goal, had an incredible shot on him was fiercely competitive, though not the all round ball player of Dalglish or Suarez.
