Sildenafil vs. Tadalafil: Which One’s Better?

Sildenafil (Viagra) and Tadalafil (Cialis) are both effective for ED, but differ in timing. Sildenafil acts fast (30–60 mins) and lasts 4–6 hours, while Tadalafil works slower but lasts up to 36 hours. Choose Sildenafil for planned activity, Tadalafil for weekend-long flexibility.
