TL;DR, Anacharis (Elodea) vs Anubias Barteri Nana
The Anacharis (Elodea) and the Anubias Barteri Nana 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 26 °C and pH 6.5 to 7.5, so a single tank can suit either one. Neither is harder than the other to keep, so the choice comes down to look and stocking rather than skill. In a low-tech, low-light setup the Anubias Barteri Nana is the safer bet; the other really wants brighter light to look its best.
