Default CO2 system and different mixes for the aquarium??

OK so i purchased a DIY co2 system called the DIY CO2 system pro from [Ebay Link Removed] In the instructions it uses vinegar and baking soda. It requires two 2L bottles, and has a needle valve and pressure gauge.. anyways.... I noticed most people use yeast and sugar mixes, and in the horticulture world i learned the yeast method as well. Is there a reason why people use yeast over baking soda? Does one last longer than the other?? or is one more toxic?? i remember the yeast method was smelly and id like to avoid the yeast method if possible. Im just not sure if i would be harming my plants or fish? any thoughts or suggestions?? sorry if this seems like a noobie question.
