Robinson's Aponogeton is a bulb / tuber plant that usually reaches about 60 cm tall by 25 cm wide. Sweet Potato is a other that usually reaches about 60 cm tall by 30 cm wide.
They also share practical benefits such as surface cover, line-of-sight breaks, and spawning sites, so the decision is not only about looks.
The strongest overlap signals are practical: they overlap strongly in placement, especially around the background; they offer many of the same practical benefits, including provides surface cover and breaks lines of sight and useful spawning site.
Why Choose Robinson's Aponogeton

The real separator is not survival, but how each plant behaves once it starts filling the scape.
If the tank already has several demanding plants, the easier choice is the one that matches your existing light, CO2, and trimming routine.
Practical Recommendation
Do not buy them as interchangeable plants. Use this comparison to decide which tradeoff matters less in your tank: care demand, mature size, placement, or visual density.
A practical way to decide is to imagine the tank six months from now. The better plant is the one that still fits the same space after several trims, not the one that only looks right on planting day.
