I think Stay Fresh Club is clearly the best, I think it's the best because it sounds the most modern and relatable. I think this slogan also helps to show what the product is about the best, it let's you know that it is going to let you stay fresh all day long. I think the other options lack that and instead make it seem like it is just a temporary thing. Therefore all things considered I would say Stay Fresh Club is the best.

I rather prefer the stop the stink club slogan because I really like the alliteration and cool and fun sound of this slogan the most and how it removes the under arm smell with clean and natural ingredients.

I like the message here that says stay fresh Club because that's a positive message and I think everybody wants to stay fresh so this would be a positive message for everyone

NOMOBO: Stay Fresh Club is the best because it actually describes the product, as in it would stay and it is long lasting. Stink is silly, and fresh spaces sounds like something for my dishwasher.

The stay fresh slogan is great because it is direct and self explanatory
