Is unifying a divison more impressive than moving up in weight winning titles?

Unifying is more impressive.

Unifing by a long shot. These days any body can win one of the many titles but few are willing and can prove they are the best in their division.

The best of the greats tend to unify a division and then move around, so i'd say unification is far more important, but to have 1 or 2 championship fights in 5 or 6 divisions and still remain unbeaten would be more impressive if we all knew for certain that it wasn't being accomplished with the use of steroids.
This is why there a can be no argument with regard to the old school greats.
