Herbal Clear is the only one that's worked well for me:
Pros: cheap, smells good, and lasts fairly long (even with three weeks of 100+ degree weather). Cons: not as effective IMO as Arm & Hammer or "normal" antiperspirants, but it's worked well enough for me.
I've tried Tom's of Maine (which didn't mask BO and gave me an instant rash) and Arm & Hammer Essentials, which I actually really liked but also caused itchiness and skin irritation. It was quite effective though so I suffered through 3 sticks before I decided I couldn't take the itching anymore. No problems since switching to Herbal Clear.
