In brief: Either
They both do the same thing - help erectile dysfunction.
Viagra (sildenafil) tends to be short acting while Cialis is long acting. There is also once daily formulation of cialis.

In brief: Equal?
Among these agents, viagra (sildenafil) has been around the longest.
It is the best studied and has the most data. Cialis is a newer drug in the same family, modified to have a long half life, or be active in the body longer. The side effect profile of these agents is slightly different and effect individuals differently. New formulations of Cialis are for daily use for both ED and prostate symptoms.
