Which everyday pen has the most verified-purchase reviews?

Among these candidates, the Sharpie S-Gel 12-count has the highest review count at over 81,000, followed by the Pilot G2 12-pack at over 54,000. High review volume paired with a 4.7–4.8 average is a meaningful real-world signal, though Amazon ratings are gameable and should be cross-checked against independent testing where available.
