TL;DR, Amazon Sword vs Jungle Vallisneria
The Amazon Sword and the Jungle Vallisneria come up together a lot when people are choosing a plant, and they are close enough to weigh side by side. Both are happy somewhere around 22 to 28 °C and pH 6.5 to 7.5, so a single tank can suit either one. The Jungle Vallisneria is the more forgiving of the two, which matters if this is an early tank, while the Amazon Sword rewards a bit more attention. In a low-tech, low-light setup the Amazon Sword is the safer bet; the other really wants brighter light to look its best.
