Care and Scape Differences
Role overlap lands at 56/100 and care similarity lands at 76/100. Treat those numbers as a shortcut for the decision, not as a replacement for looking at mature size and placement.
Amazon Sword is rooted in substrate with nutrient-rich substrate preferred and feeds mainly as a root feeder. Sweet Potato is attached / wedged to hardscape with no substrate required and feeds mainly as a water column feeder.
Care requirements are close, so the real separator is how each plant looks and 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.
