Best antiperspirant anyone?

I am currently using a Gillette gel for deodorant though I do have the problem of sweating in my underarm area. I found that Gillette does a good job of eliminating the odor as I don't have BO when I sweat but it doesn't do much in the way of antiperspirant. So I just want your opinion on what is the best antiperspirant, I used to use right guard and I think that worked well so I might try that, I also heard Mega dry is pretty good. So for the problem of excess sweating which is the best?
