RAI vs antithyroid drugs

This is from an evidence summary from AFP:

Radioactive iodine therapy and antithyroid medications produce similar health-related quality-of-life outcomes in patients with Graves disease. Radioactive iodine therapy is an appropriate choice for patients who prefer definitive treatment. Antithyroid medications are appropriate in patients attempting to avoid long-term thyroid hormone therapy and should be considered in those with increased risk of Graves ophthalmopathy, such as smokers.1 (Strength of Recommendation: B, based on inconsistent or limited-quality patient-oriented evidence.)
